Watch Service

Watches that are carried daily need to be cleaned and oiled at regular intervals. As a guideline, the maintenance programs required for watches used in railroad time service were designed to ensure that watches received sufficient attention for them to keep time reliably for decades under difficult conditions. The rules varied, but requirements for cleaning on a basis of once every year and a half were typical for a railroad watch at the turn of the century. By the mid-1920’s this was extended to two year intervals.

Service Needs in the Gay Nineties

The “Sears, Roebuck and Co., Inc. Catalogue No. 104,” Chicago, IL, 1897, reprinted by Chelsea House, Philadelphia, PA, 1968 had this to say about the need to have watches serviced on page 371:

“We Guarantee for Five Years All the movements sold by us. This does not refer to the life of the movement, but that we will for five years from date of purchase, correct free of charge any fault which may occur from defective material or workmanship. Any well made movement will run a lifetime if properly cared for.
“Remember That your watch should not run longer than one and one-half years without having the old oil cleaned off and fresh oil supplied. This must be done at the expense of the purchaser.
“The balance wheel of all modern watches makes 18,000 beats or revolutions per hour; 432,000 per day, or 157,788,000 per year. An engine or sewing machine will be oiled several times per day, but we have known people to carry a watch for ten years without having it cleaned or fresh oil applied.
“Usually, a movement thus treated is of no value, being entirely worn out. Take good care of your watch if you wish it to perform its duty properly, for it is a very delicate machine. Our charge for cleaning and oiling is 75 cents. The regular retail price is $1.50.”

Service Today

Watch cleaning and oiling costs a bit more today than it did a hundred years ago, but the watchmaker, a very skilled person, needs to be able to make a decent living. Thus, the cleaning and oiling cost reflects that fact today, perhaps more than it did back then. One message board thread addresses the wide range of costs, items covered by the service and expectations of different collectors in some detail. The quality and cost of watch service has always been an issue. Also, it may be difficult to find a good watchmaker locally and the watch may have to be sent off for service. One might think that this is a relatively recent problem, but it was an issue (albeit, a lesser issue) following World War I.

The proper oiling of a watch requires knowledge, skill and considerable care. This is explained in detail in a 1917 article on the subject. Although today's oils are better than those available almost a hundred years ago, the principles discussed in the article remain the same.

Keeping Time After Service

After being serviced, a watch may gain or lose a little bit, requiring very minor fine-tuning of the regulator. This is because each person's daily activities are different and this can affect the watch's rate. Here's what Hamilton had to say on the subject in literature distributed to its dealers:

Personal Regulation

Various factors affect the performance of any watch. For this reason, regulation of a watch to its owner's routine is very necessary. As an instance, a man occupied at a desk has a routine and habits differing from those of a mechanic; or, a typist and her routine cannot be compared to a housewife. Individually, watches worn by these persons would be subjected to widely different conditions during a day's time. And a difference in watch performance would result. Some persons do not wear their watches regularly every cay, and they allow them t lie in a flat position while not being worn. Others wind their watches at irregular intervals. Even changing a pocket watch from a trouser's pocket to a vest pocket may result in a variation of several seconds in its daily rate. In addition, small watches are greatly affected by changes in climatic or temperature conditions. Accurate timekeeping is considerably influenced by these things.

Thus, varying conditions under which a watch is required to perform, and over which there is no control explains why a new watch, or even a repaired watch may need more regulation than sometimes seems reasonable.

Most important to you, therefore, it is always advisable to explain to watch purchasers or repair clients, with utmost diplomacy, that a watch may gain or lose time during the first few weeks they carry it. This will prepare and encourage customers to return their watches once a week for comparison and regulation, when necessary. Too, it will open an opportunity to make people "watch conscious"; making them realize that accurate performance in a watch is almost wholly dependent on the care it receives from them.

Hamilton Technical Data Sheet T.D. 124 (4-Sep-51)
The average watch collector should know enough about watches to be able to regulate their watches by themselves. This is especially useful if one doesn't live reasonably close to the person who services their watches. Those who are not sure how to do so may benefit from the "Regulating A Watch" section of the Encyclopedia article on the Pocket Watch Regulator.

Here's one more thought on the subject of the watch regulator. When a watch is properly cleaned, oiled and serviced, the regulator indicator ought to be within the center 50% of its total range when the watch is keeping accurate time. Actually, it should be in a narrower portion in the center, but 50% allows for some variation of the quality of service without considering the cost of that service. If the regulator has to be positioned outside of the center 50% of its range to obtain accurate time, then it is an indication that either the watch needs cleaning and oiling, or that something is wrong with the watch. If it comes back from being serviced with the regulator outside of the center 50% of its range, it means that the person doing the service has not found, or corrected, one or more problems.

Service Frequency

If the watch is run continually, a cleaning and oiling is needed every 3-5 years. If you're only going to wear your watch occasionally, this ought to be done once at the onset and about every ten years thereafter. If you're not going to carry it (or run it), don't bother getting it serviced. Many of the watches that are kept by collectors (that aren't run) haven't been cleaned and oiled in 20 or 30 years or more.

Cheap vs. Proper Service

Don Dahlberg posted the following on the NAWCC Pocket Watch Message Board on May 28, 2006
A cheap "service" involves an ultrasonic wash of the whole movement in a combination oil/cleaner. This coates everything in oil, giving the oil a hydrophobic bath away from the pivots. Polymerized oil can only be removed by taking the watch apart, cleaning the parts in a wash, followed by several rinse solutions and finally hand cleaning where necessary. In a proper overhaul, the watch is inspected for broken jewels, warn holes and pivots and corrected where necessary. You cannot do this if you never take it apart.

In my area a proper overhaul starts at $80 and up for anything found that needs repair. Given the price of the watch, a proper overhaul and some profit, how much should your watch cost? Did you pay that much? You may get less than you paid for, but you never get more.

One more thing, if you do not run the watch, you need not clean it. When the watch is not running, the only danger is rust, so keep them away from high humidity. If you are going to run them, they should be cleaned every two to five years. Modern oils do not polymerize or evaporate as easily as old oils, but dirt still grinds away. You do not need to run a watch, when you are not wearing it. The watch is designed to keep the oil where it is needed.
