Thanks for your inquiry and the photos of your clock. I believe the base originally had a brass-plated steel center cover as do a number of clocks made just before and just after this one. It appears the cover had the center removed, probably due to rusting, and the wood inner core of the base painted to match the support pillars. Although it appears to be well done, I don't believe it is original.
Your dial, on the other hand, is definitely original Hauck. This dial has so far only be found with Hauck clocks. Based on the movement serial number, your clock was made about September-October 1906.
Also, your clock is now the lowest serial number full size movement having the Ph. Hauck Semester Uhr logo stamp. For unknown reasons this was used on full size movements before being used for the 200-Day movements that it was obviously intended to represent.
One question, could you post a photo of the upper suspension bracket? Serial number 14012 has the same movement and the Hauck No. 17 gimbal upper bracket, would like to see what your clock has for comparison.
Final question, is there a serial number stamped on the bottom of the pendulum base? A photo of the bottom will also be appreciated.
The pendulum is one of two 6-pillar gallery disc models used by Hauck from startup in 1903 until the introduction of pendulum No. 6 temperature compensating "chronometer" design and No. 19 5-pillar gallery model from the April-June quarter of 1906. After that, this particular pendulum with a relatively small diameter gallery is found being used in smaller numbers through 1907 and sparsely after that. The other design has a much larger diameter gallery with thick gallery discs that we will see later with Paul830's clock.
My main comment here is that to the best of my knowledge the mainsprings for both clocks should be identical in size and strength. The only actual difference between the two movements is the presence of the Hauck Semester Uhr logo on one and not the other. Otherwise both movements are the same. And, both are quite beautiful clocks!The one that I have has an identical dial and movement size, but is fitted with a gallery-free chronometer pendulum and its a full 400-Day variety. The serial number is 107 units higher. I must say we do not know if the main spring length and strength of both clocks are identical.
Both versions were very well made without signs showing the 200-Day version was made with inferior materials as the pictures below show.

This one with serial number 15324 is a Semester Uhr 200-Day clock and was very early in 1907, about in the middle of the production run of these interesting clocks. The pendulum "is" a Hauck, model No. 19 with the narrow 5-pillar gallery. However, it isn't correct, being made for a standard size clock made in 1908 or later. What should be there is the miniature version of the same pendulum that looks like pendulum No. 18 in the Repair Guide but with a very small 5-pillar gallery.
Glyn, thanks for posting! Based on the serial number, your clock was made right at the middle of 1912. The pendulum on your clock is the same design as the incorrect one on r72gsaol's Semester Uhr model. There is one feature on your clock that doesn't appear in Haucks made before 1911. This is a modified gimbal design that has the gimbal pivots screwed in through holes in the gimbal yoke instead of just pins riding on notches. This solved the "lost gimbal and suspension" problem. Also, there may also be an eccentric for the front plate pivot of the escape wheel arbor, first noted in late 1908.This is the clock that got me started on this addiction. I was about to come home after my father's funeral in 1999 when my stepmother said "Oh, you'd better have you grandmother's clock.' I didn't remember ever seeing it, not even a a child in England in the 1950s. But I spent several hundred dollars on a repairman getting it to run and now it does very well.
If John Hubby or someone can help me date it I'll be grateful. But I can't imagine my grandparents bought it new; they were born in 1901 and 1900. Glyn

I forgot to put the pendulum back before taking the photos!
There's no serial number on the pendulum, not even under the sheet brass insert.
The second photo is the clock in its place on the 400day clock shelf.

Paul, welcome to the NAWCC Message Board and thanks for posting your clock photos! As already noted by Eric you have a very early Hauck, made near the end of 1903 based on the movement serial number. 1903 was Hauck's first year of production, their first clocks being made about mid-year. Yours appears to be complete and original. I described the pendulum with your clock above and it can be seen that while the disc appears quite similar to the one with the narrower gallery, this callery is quite massive by comparison. So far I've not found any correlation as to why one or the other was used but will keep looking for clues. Your clock will clean up quite nicely, keep us posted on your progress as you get it restored.Hello, I'm new to the forum. I've read many posts over the years and learned so much from all your knowledge. I picked up what I believe to be a PH Hauck 400 day dome clock. It is stamped with serial number: 1323. I've enclosed several pictures please let me know your opinions.

Thanks so much for your help. Paul
Did you catch the sale price?This Hauck Louvre sold yesterday: https://www.liveauctioneers.com/item/43199172_vintage-torsion-pendulum-clock-under-dome. Hard to be sure, but the serial number appears to be 31934.
That's a low considering the chronometer pendulum. I'd say someone got a good deal.Sale price was $500 plus 21% juice so total was $605 and depending on where you live sales tax. This doesn't include packing and shipping of at least another $100.
It was interesting and probably scarce in this form.
No luck finding a small semester uhr pendulum. Does anyone have the dimensions of the disc? I am going to make one on the lathe, It won't be right but it will look close enough for now.Next, we'll look at r72gsaol's new acquisition:This one with serial number 15324 is a Semester Uhr 200-Day clock and was very early in 1907, about in the middle of the production run of these interesting clocks. The pendulum "is" a Hauck, model No. 19 with the narrow 5-pillar gallery. However, it isn't correct, being made for a standard size clock made in 1908 or later. What should be there is the miniature version of the same pendulum that looks like pendulum No. 18 in the Repair Guide but with a very small 5-pillar gallery.
Polly, thanks again for posting your clocks, and congratulations on the superb results you obtain in restoring them. This one was made right at the end of 1909 and has Plate 1607 with no logo or other identification, as well as the typical Hauck upper suspension bracket No. 17 as shown in the Repair Guide.For the records I have a couple of Ph. Hauck 400 day clocks. This one is serial number 26717 the chronometer style pendulum is un marked.
This clock also has Plate 1607 with no identification marks and was made right at the end of 1911 based on the serial number. It has the same upper suspension bracket but a much larger dial than the first clock.The other serial number:- 34439 once again the pendulum is un marked.
The pendulum has a black mark where a monkey had fitted a steel washer to slow the clock down, I removed it but the stain would not budge.
Very late response, was flooded out just four days after your post, fortunately most all of my collection wasn't affected.I've got the clock restored and running. I came up with a very well made reproduction pendulum at the Eastern States Regional. I've been using a tumbler to polish the parts and it's very effective 24 hours and the parts are bright and shiny again.r72gsaol said: ↑
I picked up this little guy today. Hauck Plate 1632 I believe. The guy I bought it from said that it did not come with a pendulum but got this pendulum from Charles T. as what he thought it should be? I don't see how it could be correct.

John, There are no extra numbers on the edges of the plates. The nearest number I've recorded to this one is 13506 which had a Urania dial.Eric, by any chance is there a Grivolas serial number with star stamped on the left edge of the back plate? This movement is within the serial number range of the last Hauck movements purchased by Grivolas for their "German" Grivolas clocks, which were all used to mount in crystal regulator cases. Based on the serial number it was made about August 1906.
The miniatures in my Plate 1599A data have serial numbers from 16 to 433, the Plate 1631 clocks are from 513 to 895. There may be some overlap with these standard size movements on either side that will come to light, but it certainly now appears that Hauck first produced the rectangular plate miniatures, then these standard size models (that have a slightly different plate layout from later production as noted above), then the round plate miniatures, then the standard Plate 1610 design clocks, for which the lowest serial number found so far is 935. All this occurred within the second half of 1903.NOTE that the illustration for Plate 1599A in the Repair Guide is much too large and completely wrong. The actual plate size is 2 inches x 2-3/4 inches.
Kamil, you may have missed my note above that says "NOTE that the illustration for Plate 1599A in the Repair Guide is much too large and completely wrong. The actual plate size is 2 inches x 2-3/4 inches." The actual rectangular plate is 1/8 inch shorter than the diameter of the round plate model, Plate 1631. Here are some photos, first the rectangular plate model and then the round plate:Dear John , what do You mean that plate 1599A is a miniature. It looks in the 400 book like a standard plate movement, but different to the one presented on pictures above? Please can You share some pictures of the early rare round movement Hauck and a rectangular early plate clock.
I have just come into possession of this clock 2 days ago. I think it might be the Hauck serial number 463 that you mentioned John. However I do have some questions about it. 1) The pendulum appears to be Jahresuhrenfabrik #21 (thus explaining why I thought I was getting a Jahresuhrenfabrik clock, 2) I don't know what to think about the serial number appearing to b superimposed upon a different number 3) is there a matching plate in the Terwilliger guide?Actually, this is nothing less than incredible!! I've been documenting Hauck clocks for over 20 years and had not seen any full-size movements made with serial numbers lower than 935. Now we have two with very close serial numbers, this one 476 and the other that I mentioned being 463. It is notable also that the back plates of these clocks, while quite similar to Plate 1610, are NOT the same. The third wheel pivot for these two clocks is planted 3 or 4 mm higher than the fourth (center) wheel pivot, whereas for all clocks with Plate 1610 and later the two pivots are on the same horizontal line.
Once again, thank you for taking the time to share your knowledge on these clocks. For the record, with my magnifier it looks like 463 stamped over 553 for the serial number. This is very exciting for me! To date my collection has ranged from "collectable" to "hey it looks pretty when it spins". I'm looking forward to making this one spin too.MJ, thanks for posting the photos of SN 453 Hauck. Interesting to see that the serial number has at least the first number over-stamped and possibly the second digit as well. At the time these were being made the serial numbers were being stamped by hand, and it really isn't uncommon to find over-stamped numbers. I think you are right that the original number was a "3", but I can't really say what the second one was IF it is actually over-stamped. I've put a note about this in my database, but my "convention" when I find over-stamped numbers is to record the last number stamped as being the correct one.
Regarding pendulum No. 21, it actually was not invented or made by JUF. We don't know for certain who actually designed this pendulum, but the first documented use was by Andreas Huber when he started making 400-Day clocks in late 1896. Huber then used only pendulum No. 21 until he invented the Pendulum No. 10 twin-loop temperature compensating pendulum. Even then, No. 21 is found on the large majority of Huber clocks. Huber stopped production of 400-Day movements in early 1904, instead buying movements and complete clocks from JUF, Hauck, and Kienzle.
JUF also used pendulum No. 21, as did Ph. Hauck. Hauck, as seen for this clock, used this pendulum from 1903 to 1905 for a number of their clocks, although the majority of their clocks had their own design disc pendulum. JUF started using the No. 21 around 1898, then by1902 used it for most of their clocks until the end of 1904. After that they had their own simpler design.
Both JUF and Hauck also used pendulum No. 10 under license from Huber, JUF from 1902 to mid-1907 and Hauck from 1903 to mid-1906.
From my research I believe your clock is complete and original including the pendulum. I have the identical clock model documented that was made just a few months later, serial number 1166, that also has pendulum No. 21.
Mjstewart, thanks for posting the higher resolution photos, much appreciated! Also pleased that you found the "483" serial number stamped in the mainspring barrel, you are correct that would be the actual clock serial number.Thanks Kamil, I knew there was something wrong there. My Ipad wasn't playing nice. I will repost them here.
Good news, inside the barrel is a clearly stamped number 463 so I take that as the honest to goodness serial number. Bad news is the barrel is full of green gunk and a mainspring fractured into 3 pieces. Would I be right in assuming that the 19x36 spring listed for plate 1610 as a good fit?
Peter, thanks for posting! This is a really nice example of the Hauck miniature with rectangular plates.Here’s my PH, number 433.
Hi Bod,Hi, another for the collection. View attachment 522715 View attachment 522716 View attachment 522717 Can you spot the problem?
All the major parts are stamped 91, the pendulum is handwritten with the serial number in an old fashioned script, which looks original.(29091)
There are 3 different menders marks on the base of the pendulum, so it's been worked on in it's history.
View attachment 522722 (Tips on how to rotate picture appreciated)
The anchor arm has been bent. Is this screwed or glued in?
The clock came to me with no suspension, but via E bay, a gimbal from Australia, fork from India, and a suspension from the USA, it's now working!
A 0.0034 suspension only allowed it to run at -1 hour per day, a 0.0040 suspension now has it within adjustment range.
The clock has been in storage wrapped in damp white paper, which caused light rust on the pinions, now removed.
Should this be a good runner, later in the summer, a strip down and polish will happen.
Bod
