This has an integrated detent spring which holds the setting lever in either the winding or setting position. The most significant part for identification is the largest part, the cover plate. For example, The Bestfit Book includes the diagram shown here of the parts of the keyless work of ETA calibre 715 and Eterna 710. Bestfit 1965 ETA 715 and Eterna 710 The keyless work under the dial that handles stem winding and setting is often said to be the 'fingerprint' of a movement. Manufacturers altered the appearance of their movements by changing the top plates, but the basic layout remained much the same. In fact, the apparently huge variety of Swiss watches is explained by this phenomenon: once the basic layout in a round movement of the barrel, train wheels, escapement and balance was arrived at, there was little scope, let alone need, to change it.

Although some movements such as the IWC calibre 64 leap out to the experienced eye, other are less easy because of similarities between the products of different manufactures, and manufacturers altering bridge shapes for different customers. It is often difficult to identify movements from the shape of the top plates or bridges alone. The idea of this page is to try to identify otherwise unknown movements found in the type of watches that I collect, which are principally Great War era men's wristwatches with 12 or 13 ligne movements. I don't intend to show movements with their makers names on them, because they are already identified. It is a small selection of often unidentified old movements that I have been able to positively identify.

Perhaps someone with more information will respond. What I have seen sell in antique malls is $100-200 if gold filled, $300-500 if solid gold. You did not mention the size or if it is open face or a hunting case watch. I think a 20 year case is 10k goldfilled and a 25 year case is 14k gold filled. If the inside of the cased is marked 'warranted' it is most likely gold filled. Also, I would guess that a 15 jewel is probably gold filled. I think Elgin was probably playing off the railroad theme. Value depends largely on whether it has a gold case or a gold filled case.Ī 15-jewel watch is not officially a 'railroad' watch. If it is still bright and shiny, then it is a platinum metal. If it is dark and dirty looking (no worries, it cleans off) it is whit gold. If you are able to carefully heat your item to red-hot then let it cool, you can tell by how it looks which it is. If your item is easily scratched on a place that is normally not seen it's probably gold. Also, white gold is much softer than platinum. If you are not able to do these tests on your own, a jeweler will usually be happy to do the testing for you if they have the time. The best way to tell the difference is, of course, by testing either by acid or electronic tester. Hi.I'm not a watch expert, but in my experience, numbers such as 73069d are usually serial numbers.

You may sometimes here that Eatons pocket watches have Rolex movments, but that seems to only be their '1/4 century club' presentation watches (and it's somewhat moot anyway because Rolex didn't make Pocketwatches, they bought mostly from Cortebert and just finished them in house). That would suggest that yours is from the 30's or 40's. The one I have is serial 177698 and is (i believe) from the 1920's. Most Eatons pocket watches were imported from Switzerland, and were originally made by Gallet. Especially the movement serial number, in case they can't be seen in the picture(s). I am trying to find info on a Gallet pocket watch.
