Waltham Watches

The Watch Companies of Waltham

The watch companies commonly referred to as "Waltham" have undergone a series of name changes:

Pre-Waltham Watches:
Boston Watch Co.
Tracy, Baker and Co.
Appleton, Tracy & Co.

Waltham Watches:
American Watch Co.
American Waltham Watch Co.
Waltham Watch Co.
Waltham Watch and Clock Co.

This succession of companies (or in some cases, the same company under a different name) made a full line of watches ranging from modest, affordable watches to some of the finest watches made in this country. As can be seen in the articles listed above, the companies had their origins in the 1850's. For convenience of the following narrative, all will be referred to as a single entity, "Waltham." It was the first successful company in America to manufacture watches in mass production using machinery to make identical (or at least, near identical) parts. Over the next hundred years or so of its existence, its output of jeweled watches (over 34 million) was only exceeded in the U.S. by one other company, the National Watch Co. at Elgin, IL.

The business history of the Waltham Watch Company is detailed through 1945 in Timing a Century by W.C. Moore, 1945, Harvard University Press. This book is in the NAWCC Lending Library. It was commissioned by Waltham in 1941 and was turned into a case study for the Harvard Business School. In addition to the corporate records and interviews, Moore made use of an 1883 manuscript written by W. H. Keith. This manuscript is preserved as a PDF through the generosity of Richard Watkins and can be found here: http://www.watkinsr.id.au/Keith.pdf

After Robbins Sr. stepped down in 1883, Waltham had continuing problems with operating capital and loss of market share to new companies. This involved several changes in stock and ultimately, in 1923, the banks stepped in and installed new management and a sound financial structure that served Waltham through the Depression and WWII.

Basic Movement Information

Some basic facts about a Waltham watch can be found by entering the serial number on the movement (the "works") in the field on the Find Serial link accessible from the NAWCC Waltham Serial Number Database. Commas should not be used in entering the serial number.

There is also a Waltham Database Glossary of the terms provided by the serial number lookup. Note: When a number appears by itself in the Comment Column, it is the page in the factory serial list where the entry and explanation appeared. i.e. "Comment 42" is on page 42 of Serial Numbers With Description of Waltham Watch Movements,, (commonly referred to as "The Gray Book").

Approximate Production Dates

Should the date not be listed in the search of the NAWCC Waltham Serial Number Database, Oldwatch.com's Waltham Production Date Chart, or the Pocket Watch Site's Waltham Date Table are a means for determining the approximate production date. In general, we think of serial number vs. date lists - created by using the average number of watches produced over a period of years - to only be accurate within a year or two at best, and recognize that there are numerous exceptions wherein which the dates may be off as much as 3 years or more. This is not just for Waltham, but for other watch manufacturers as well. Getting back to Waltham, the accuracy of serial number vs. date tables is discussed in a message board thread entitled "Waltham production dates," started by Jerry Treiman in September, 2010.

Model and Grade Report

The NAWCC Waltham Serial Number Database has a search feature that will show the runs of Models, by Grades. Click on "Search" on the top menu bar to bring up the General Lookup Page page. By using the full model number (i.e. 1883) and a specific grade (i.e. 35 - for grade No. 35) in the query fields, a report is generated showing a summary of the different versions (hunting-case, open-face, etc.) and a full list of runs. However, the grade names for runs weren't consistently identified. Working with the above grade (No. 35) as an example, some runs are identified as plain "35" while others are identified as "No 35". For other grade names, the names or abbreviations aren't necessarily intuitive. For best results, run the search of a model using a percent symbol (%) in the Grade field. This will generate a list of all of the grade runs for that model. Looking through the list will provide you with the name(s) of the grade of your interest. You can then rerun the search using that/those name(s).

Waltham's Jeweled Main Wheel

In 1907, Waltham announced that its watches marketed for railroad time service were then fitted with a jeweled main wheel. These jewels are internal to the mainspring barrel and are not visible unless the barrel is disassembled.

Model 1859

The model 1859 or KW18 was intended as a high grade thin model watch, possibly in anticipation of imminent competition form E. Howard & Company. It was developed by N. P. Stratton shortly before he left Waltham to start up the Nashua Watch Co. with Woerd, Moseley, Bingham and others.

Waltham produced the 1859 model in the American Watch Co. grade and in the Appleton Tracy grade as a high end watch for a couple of years but stopped the high end production when the Nashua group was reabsorbed back into Waltham and the KW20 replaced the KW18 as the high grade watch.

The 1859 model was produced in the Wm. Ellery grade (ed. note: posted by Ben Hutcherson) during the Civil War and was marketed to the Union forces. Other than being thinner than the 1857 model, and being set from the rear, it had no particular advantage and was eventually dropped from production since it was a diversion and more expensive than the 1857 model.

The 1859 model was Waltham's first model with mainspring protection. Fitt's patent mainspring protection was applied to the American Watch Co. and Appleton Tracy grades of the KW18 but not the Wm Ellery grade. It was also used on the KW10 ladies watch in both the Appleton Tracy and P. S. Bartlett grades.

Appleton, Tracy & Co. Gilt Damaskeened Movements

A number of model 1883, Appleton, Tracy & Co. (AT&Co) grade movements were built having a gilt damaskeened finish; a finish in which the plates were gilded and damaskeened. These were made in both hunting and open-face versions and in both 15-jewel (example posted by Dave Coatsworth) and 17-jewel (example posted by D Magner) configurations. These may have gilt trim, or polished steel regulators and screws, or blued screws. Although not as common as the gilt or nickel finished movements, the gilt damaskeened finished movements are frequently seen and are not considered to be uncommon.

Serial number vs. grade data originating from the best source to date, the NAWCC Waltham Serial Number Database, which is largely based upon "The Gray Book" (see References - Books, below), frequently fails to distinguish between runs of gilded or nickel-finished AT&Co grade movements, nor does it always note if movements have the gilt damaskeened finish. In fact, for a large number of examples it also fails to note that the movements were built (or re-built) as 17-jewel movements. These gilt damaskeened AT&Co grade movements appear in runs that are not entirely made up of gilt damaskeened movements, or even entirely AT&Co grade. Some serial numbers are from runs that are listed as P.S. Bartlett grade.

A very partial listing of serial numbers and configurations may be seen in the Message Board thread entitled "Waltham AT&C Gold Flash."

Those having, or recording data on, examples of gilt damaskeened AT&Co grade movements should use the Observation feature of the NAWCC Waltham Serial Number Database to report them so that the information available on the Database can eventually be improved.

Appleton, Tracy & Co. Premier

Waltham's description of the model 92 Appleton, Tracy & Co. (AT&Co) grade can be seen in this February 1902 Ad. At that time it was accepted into railroad time service, even though it was adjusted to only three positions (which was considered adequate in 1902). When the model 92 Appleton, Tracy & Co. Premier grade (always marked "Premier" on the movement's barrel bridge) was introduced later in 1902, it's description showed it as being adjusted to five positions. The Appleton, Tracy & Co. Premier immediately took over the "plain" AT&Co's place in Waltham's offering of railroad watches, as seen in this 1903 Ad. Interestingly, as brought out in a February 2009 NAWCC American Pocket Watch Message Board Thread, the model 92 AT&Co movements seem to have the name "Tracy" misspelled as "Trary." However, the font that Waltham chose used a style for the letter 'c' that made it look like an 'r'.

Grade No. 35

Waltham's grade No. 35 is a movement that is frequently underappreciated. It is unknown to novices and even to intermediate collectors. This 15-jewel (and later, 17-jewel), 18-size, model 1883, damaskeened nickel watch tends to remain unnoticed in marts. In fact, some dealers have been known to have one or more examples on their tables and not even be aware of it. The reason for this is that unlike the Crescent St.; Appleton, Tracy & Co.; P.S. Bartlett and others; the No. 35 grade falls into the category of watches generally known in the watch trade as "Nameless" grades. The grade number isn't marked on the movement, which only bears the signature "American Waltham Watch Co." and the "Adjusted" and "Safety Pinion" markings, just like a number of other grades. The only way to determine if a nickel, adjusted, damaskeened nickel, model 1883 movement is a grade No. 35 is to look up the serial number, either in the reference books or as described above.

Yet in 1887, it was listed as being "Adjusted to Heat and Cold, and in all Six Positions" and at $36.00, it sold for considerably more than the gilded Appleton, Tracy & Co. grade ($30.00). This is the grade of watch used by the well-known Illinois Central engineer, John Luther Jones (well .... , he's better known by his nickname; Casey). Despite being a "Nameless" grade, the No. 35 was specifically promoted for railroad time service use.

The grade No. 35 was made in both hunting-case and open-face versions. It was first released in 1886 as a 15-jewel movement. In 1894 or 1895 it became a 17-jewel movement and stayed on the market for a few more years. There were a variety of damaskeening patterns used, some of which were the pleasing "frosted" damaskeening. Also, the grade No. 35 was one of the first watches that Waltham offered in a Non-Magnetic version, see the "Waltham Non-Magnetic Watches" section below.

The production quantities are listed below, but a certain amount of inaccuracy is inherent in the values, although the overall total is fairly correct. This is because an indeterminate number of movements were upjeweled from 15 to 17 jewels, probably as a result of market share being lost to Dueber-Hampden's 17-jewel-watch marketing blitz, see the "The 17-Jewel Watches" section of thr Hampden Watch Co. Encyclopedia article. Neither records of the serial numbers, nor the quantities, of the up-jeweled movements appears to have survived. Thus, there are a number of 17-jewel No. 35 movements that have a serial number which, when looked up in the references, are recorded as being produced as 15-jewel movements.

The Riverside Grade

Over the years, the Riverside grade was made in a variety of different sizes, models and jeweling. A survey of these models is presented in the Message Board thread entitled The Riverside - Waltham's most popular movement grade". A fairly high grade, the Riverside was usually positioned just below the top grades in larger-sized movements. The 12-size Riverside variants are pictured and discussed in this message board thread.

Grade No. 1621 Riverside

The Waltham Riverside grade No. 1621 is so-named (by Waltham) because it is 16-size and is fitted with 21 jewels. This movement is widely recognized to have been adjusted only to temperature (especially since it is marked as such on the barrel bridge). The Gray Book (see References section) identifies (at least most of) the runs, some of which are pendant-set. Not being a high grade watch, and being value engineered, they are only fitted with a plain regulator. Thus, having been built starting in the mid-to-late 1930s, not being adjusted to at least five positions and not having a micrometer regulator, the Riverside No. 1621 would not have been accepted into railroad time service.

Some early examples from the late 1930s have been seen with double-sunk dials (including Montgomery dials), but the vast majority had single-sunk, imitation double-sunk, dials (more properly referred to as "Inner Circle" dials), marked "Waltham - 21 Jewels." Its hard to say if those early ones came from the factory with double-sunk dials, or had them added post-production. Occasionally, the dials might also be marked "Special Railway" or "Railway Dispatcher." There may have been other, additional names. Also, in the very late 1930s and early 1940s, Waltham marked both the dials and cases as "Premier." The early production of the 1621 Riverside movements are damaskeened in the classic manner. This disappeared as the demands of wartime production required reductions in labor.

The 1621 Riverside was sold as a complete watch in a factory-marked case with a single lever slot at the 56 minute position. Its intended market was probably transit workers and those railroaders not under the time service rules. It is suspected that a large number of Waltham-signed factory cases were stripped off of the 1621s by collectors and dealers, and used as replacements for the 1623 Vanguards, whose cases were worn through to the brass.

Grade No. 1623 Vanguard

The 1623 designation was a grade number that Waltham assigned to their 16-size, 23-jewel Vanguard grade movements. Initially, these were built in the 1908 model. As explained in a January 2013 Message Board thread, a new model, the model A, was introduced and the Vanguard grade No. 1623 began to be made in the model A around serial number 32,054,001. It is believed that the model change is characterized by the use of a new regulator design in place of the 1908 Ohlson regulator. The serial number seems to have been moved from the barrel bridge to the pillar plate at the same time. Both changes can be seen on serial number 33,370,573.

Waltham's grade No. 1623 Vanguard started being built in the mid-to-late 1930s and remained in production until the end of watch manufacturing at Waltham in the mid-1950s, as seen in cuts from Montgomery Ward (U.S.) and Eaton (Canadian) Catalogs. One feature that characterizes the No. 1623 Vanguard from earlier Vanguard grades is the location of the setting lever at the 56 minute position. However, it appears that the earliest No 1623 designated movements might have had their setting levers at the more typical 6 minute position.

During the span of serial numbers of about 29,375,xxx - 31,330,xxx the No. 1623 Vanguard was fitted with Waltham-marked dials and cases which were also marked "Premier" (which was, as pointed out by Larry Treiman in an April 20, 2011 message board thread, a "... designation (used) on virtually every watch in their line, from the cheapest 9-jewel wrist watch on up to the top of the line."). However, it is only the serial number that seems to distinguish watch movements with dials and cases so marked, from those made before and afterwards. Literature hasn't appeared that differentiates the “Premier” marked No. 1623 Vanguard watches from those lacking the “Premier” marking.

The earliest No. 1623 Vanguard movements were damaskeened in the traditional manner. This gave way to a simple bar pattern. The bar pattern disappeared during WWII production (probably to reduce labor) and was applied again to those watches made after the war. It was also during the war (about serial number 31,331,000) that the adjustment marking changed from "Adjusted 6 Positions" to "8 Adjustments" although this was just a different way of stating the same thing. Waltham ads, such as one from 1952, indicate that 8 adjustments included adjustment to six positions. A 1954 ad states that the watch had "9 adjustments (6 for position, 2 for temperature, one for isochronism)." The claim for the 9th adjustment was superficial as isochronism was inherent in the design. It should be noted that the movements themselves continued to be marked "8 Adjustments." Regardless of the claimed number of adjustments, the No. 1623 Vanguard was universally accepted for use in railroad time service.

The No. 1623 Vanguard was a "value engineered" watch. It was designed to provide quality timekeeping rate at minimum cost. They were furnished with single-sunk, inner circle dials. Eventually, painted dials were supplied. The more expensive screw-down jewel settings of the earlier Vanguard grade watches were eliminated, as was the fancier damaskeening. Even the use of the state-of-the-art, rust-resistant, anti-magnetic "Correlator Balances and Hairsprings" with the cornel hairspring and monometallic balance reduced the cost by eliminating the more expensive bimetallic, conventional expansion balance. And the cost needed to be reduced as there was tough competition in the post-WWII era with $71.50 being the going price for a railroad watch. The No. 1623 Vanguard was sold as a complete watch in a factory-marked case with a single lever slot at the 56 minute position. However, movements only were available to retailers and for export to Canada, as seen in cuts from Montgomery Ward (U.S.) and Eaton (Canadian) Catalogs.

Canadian Pacific Railway / Canadian Railway Time Service

These watches are discussed, with tables, of examples in the Waltham's Canadian Railway Movements Encyclopedia article.

Those Assorted Special Runs

The book Serial Numbers With Description of Waltham Watch Movements (see References, below) shows a number of runs whose grade is only identified with the notation "Special" or "As'st Spec." One of these runs may be a mixed run, consisting of a number of different sizes or models, or it may be comprised of a single size and model created for a customer as a private label watch. An example of one of the runs noted as "Special" is the serial number range of 16106101 - 16106300, from which model 1899, 21-jewel, open-face, lever-set movements, adjusted to five positions, bearing a damaskeened gold-on-nickel finish, labeled "Signal" or "Special W.C." have been reported.

Another example is the run in the serial number range of 17187501-17188500 designated as "As'st Spec." It contains movements labeled "J. Q. Hatch" as well as 18-size, model 1892, 17-jewel, lever-set movements, adjusted to five positions. Reported examples of these model 1892 movements in the range of 17188101-17188300 bear the Canadian Pacific Railway Beaver & Shield herald while the range 17188301-17188500 contains examples labeled "Made For Canadian Railway Time Service" (see above).

The runs designated as "As'st Spec." are discussed, with a table of reported labeling in an article by Jerry Treiman on the Pocket Horology Chapter 174 website entitled "Waltham's Assorted Specials."

Waltham Non-Magnetic Watches

Starting in 1887, Waltham offered Non-Magnetic Versions of some of its movements. At the same time, it offered a service to refit watches already in the field with non-magnetic parts. In 1889, Waltham's line of non-magnetic watches was expanded. By 1891, at least one mail-order house was offering a Waltham Non-Magnetic watch for use as a railroad watch, accepted for use in railroad time service.

In 1893, Waltham promoted the model 83 (the model 92 had yet to be introduced), non-magnetic grade No. 40 for railroad use. This grade was available in nickel or gilt finish and in hunting-case or open-face versions. In 1897, a non-magnetic, 17-jewel, model 92 movement was available as the grade No. 45. Being adjusted to temperature and position, it would have been suitable for railroad time service at that time. An uncommon 15-jewel, non-magnetic, model 1892 (made for use on the New South Wales Government Railways) can be seen in a late 2011 Message Board thread.

Also in 1897, the “Sears, Roebuck and Co., Inc. Catalogue No. 104,” Chicago, IL, 1897, reprinted by Chelsea House, Philadelphia, PA, 1968, had this to offer:

NON-MAGNETIC WALTHAM Movements will be furnished in 18 size only at the following additional prices: For the 7 jeweled grade, non-magnetic, add $2.50 to the regular price. For the Crescent Street add $5.00, For the Vanguard add $5.00. A special grade 15 jeweled nickel, adjusted to temperature, isochronism and position, will be furnished for $7.00 more than the Bartlett.

Interestingly, a letter from E.C. Fitch, then president of Waltham, to Robbins & Appleton (the exclusive agents for Waltham watches) dated December 18, 1903 stated, with regard to non-magnetic watches, that Robbins & Appleton should list non-magnetic watches in pendant set only "... to discourage use on Railroads and confine them generally to electrical people, ...” since the non-magnetic watches took longer to adjust to temperature and positions. (Letter #804, Volume P-2, Waltham Watch Co. Collection. Baker Library, Harvard Business School). It appears that this was still in effect in 1906 when Goldsmiths' (a Canadian jobber) issued its 1906-7 Price List. Page 14 clearly stated that open-face watches (the type which were most likely to be used in railroad service) were available in pendant-setting only.
