Need help with pocket watch case tubes


Recommended Posts

Hello I was wondering if anyone can send me a link to where i can buy stem tubes or case tubes for pocket watches. I have seen them for sale on ofrei and caskerco but not sure what Iam buying. Some are made for where the bow is and a lot of what i see is for waterproof crowns. I need the tube that attaches to the case where the crown sits. I have a pocket watch I want to convert to a wrist watch it is a size 12 Elgin i already soldered the Lugs but i need the crown to not have such a long neck, i have seen these conversions before esp during Great War period and I have seen the crown is seated against the case like a trench watch. I figured i would have to cut the neck or tube a solder a new tube into the case. I will then have to thread it and install the correct case sleeve and stem. I just need to know what needs to be purchased in order to do this. Does anyone have experience with this.

    • Here is the insert ring for rectangular or elliptical movements: Note that the length is the side with the stem cut out on the spreadsheet (in the picture below this is 15.15: Here is the fake pdf file, again you need to convert to .zip after download to access the FreeCAD and 3mf files.

    • as you took the mainspring out what did it look like? It's amazing how much amplitude you can get if the mainspring actually has the proper shape. last week I was doing a 12 size Hamilton and was very much surprised with the beautiful back curvature the mainspring had. Then the watch had a really nice amplitude the group would be so proud it was 350 until I dropped the lift angle down to 38 that drop the amplitude quite a bit below 300. then with the beautiful back curve it still had really nice amplitude the next day. I really wish all my mainspring's look like this as the watch had beautiful amplitude the next day. So many of the aftermarket pocketwatch Springs I see now do not have anything resembling a back curve may be a slight curve and that's about all. They still work but they just don't work as nice as a properly made spring. then Omega as all sorts of nifty technical documentation unfortunately every single corner is watermarked with where it came from who downloaded it etc. very paranoid company. On the other hand I will snip out images like from the document on recycling a mainspring barrel. for instance here's the section on what your mainspring should look like. water damaged a lot of times means rust was there rust on this watch?
    • I dont understand why a patreon membership would have limited places ??
    • Welcome to the forum, enjoy. It’s highly unlikely you will be able to purchase a new bezel look on eBay for a pulsar watch for repair to find a bezel.
