Need help with this Louis Jacot pocket watch

This small pocket watch (34mm case) was made by Louis Jacot. It has a coin silver case and is pin set. Although there is no engraving on the movement, the outside of the cuvette is engraved N. 10013 Ls. Jacot Locle. The inside of the case back is also engraved 10013.

I found an article online that says "Loomes lists Louis Jacot Locle as 3rd quarter, 19th century." That would date this watch to around 1865-75. However, I just checked my own copy of Loomes (which I just ordered), and it gives different information. Although it shows several watchmakers with the last name of Jacot who worked in Le Locle, Switzerland (i.e., Emile, Charles Edouard and A. Henry), it lists Louis Jacot as having worked in Birmingham (Warx) from 1886-93.

This leaves me confused. Can anyone tell me when this watch was actually made? Also, is the Louis Jacot who's listed as working in Birmingham the same Louis Jacot who made this watch in Le Locle?
I understand that Le Locle is known as a center of Swiss watchmaking.

Regards,

Jon

1865 to 1875 is reasonable. L. Jacot was probably a broker/retailer. It is a less common movement thatn the more usual Geneva style but common enough that it could have been the product of numerous specialists on order for L. Jacot.

L.Jacot did not make the watch. He bought ro00ugh movements had contracted various specialists to finish and provide dials and case watches, much like English retailers did at the time.

It is hard to see in the photos but the regulator is marked A and R indicating French market so Birmingham is very, very unlikely

There were a lot of Jacots in the watch business then and probably now.

I'm not able to open the cuvette since it's closed tight and I'm afraid of damaging it. However, there is a hallmark engraved on the inside of the outer case (in addition to serial number 10013).

If you have a copy of Philip Priestley's Watch Case Makers of England, it looks a lot like Maker's Marks Cameo type 21 that is found on page 89 (shaped like a horizontal figure 8). Does that help at all?

Best,

Jon

I don't have Priestly's book, however, this watch is almost certainly Swiss, not English. The case, I suppose, could be English made, but it would have many more marks than just one. The photo #3 of post #1 shows the cuvette being open. Are those not your photos?

Here's one example of a 'horizontal figure 8', this example being German in origin:

Hi Squite,

No, that's actually a photo showing the outside of the cuvette (with the cuvette closed). The hallmark on the inside of the outer case is very difficult to photograph since it's so small, but it looks like the picture below (which was taken from Priestley's book).

If I have any luck opening the cuvette, I'll be sure to let you know what I find!

By the way, I do agree that this watch is most likely Swiss.

Best,

Jon

No Jon, I think you may have misunderstood what photo I was referring to. Photo #3 shows the movement. Clearly the cuvette is open if we can see the movement. Not that it matters much as the photo from Priestley's book does help to clarify a bit.

Oh, I see what you mean. Yes, that photo does show the cuvette open, but it was taken by the person who sold me the watch. I'm going to try again to open it tonight, but it was stuck pretty tight and I don't want to take a chance of damaging it.

It's just friction fit. There is no latch on it (it is hinged, of course). You'll probably need to pry it open....carefully! Also, I'm pretty sure you're not supposed to use a seller's photos unless you have their specific permission to do so.

I also saw that a Louis Jacot, watchmaker, was born in 1860 in Le Locle and fathered Emile, Bernard, and Paul all in Le Locle. I doubt he would have made a watch at age 5.

Hi Bill,
What type of movement is it in this watch?
You've happened upon a thread from 2013, but if you mean the watch in post #1, it looks to me very like a cylinder in a 'Lepine' calibre Swiss movement. This name is generic as applied to these watches, they weren't made by the famous French watchmaker but he originated this design, using a separate cock for each wheel in the train to make a much slimmer movement.

Regards,

Graham

Graham, thank you so much for your kind response. This will help me in reassembling an almost identical watch. Kind regards Bill

Hi Bill,

These watches are pretty straightforward, apart from the hanging barrel, which flummoxes some who haven't seen one before. The snail on the barrel arbor is screwed on with an RH thread rather than being integral, so it has to be unscrewed before you can separate the barrel from the bridge.

Regards,

Graham

Seeing that we seem to have hijacked this old thread, I just picked up a very similar watch, but in gold plate and signed "Louis Dubois"(which I admit, is why I bought it. It was inexpensive and had my last name on it :)). I'm guessing that these watches were assembled out of parts made by various craftsmen about Locle, as most examples I can find with google were signed by Louis Jacot but there are also enough of them which have very similar cases, dials, and movements, but signed by others.

Out of curiosity, does anybody have any reference that has info on this Louis Dubois?

Pritchard's book has severfal entries on L, L.A. and Louis Dubois but not much substantive 9information. IT shows for trademarks of L. A. Dubois, crossed canna winged horse Neptune with a trident and a flying crane.
