Early Snow Scene

I was asked to look & see if I could get working again a friends watch that was his fathers . It is a Rotary with a Peseux 320 movement.

I always put such watch on my Timograph just to see what I am up against well see below.

The big issues with this watch was getting the back off to say the least it was very difficult & I had to prise it off using my case opener tool. This tool is invaluable with a tight case back

 

Not my one but the same design

The other issues was the movement was very,very dirty & it was a mile out of beat (9.0 ms). The cleaning assembly & lube very straight forward but adjusting the beat was tricky as adjustment was only achievable by moving the hairspring collet. However this pic was after a few tweeks.

I did eventually get the beat error down to 0.8ms  & settled for that. Fitted a new high dumb cystel job done apart form a new strap required.

Nice to see another watch saved from the bin,  it looks like new.   I sometimes found that the winding button on watches that had been well used had started to become smooth or were too small to wind comfortably,  a new button/crown made a big difference to how easy it was to wind up,  just my thoughts.

Good point will ask the guy when I see him if he would like that although this one is not to bad.

Nice job but as its not s/second wouldn't a "low dumb crystel" been better. :D

Maybe but I am sure my friend will be more than happy with the result. He might actually buy me a few beers (hopefully)  :woohoo-jumping-smiley-emoticon:

OK 

The main tweek was the hairspring was contaminated with something that the watch cleaning machine did not shift. So I removed the hairspring from the balance  & soaked in one dip. After approx. a dozen moves with the hairspring collet got it with a reasonable  beat error.

 

After these I ran the watch for an hour or so before the final regulation. Since then I have attached it to my watch tester for 24hours just to double check all was well. And that,s it no more comments please  as I have some serious wine drinking to pursue this evening.

    • Showing state of hairspring on receipt, backplate & 'dished' wheel. 
    • I would harden and temper (to a light blue). It's so easy to do and only takes a couple of minutes. A search on ebay UK for "spring steel strip cs" finds plenty available in small quantites and thicknesses from 0.1mm up.  But the question is ( @nickelsilver) which "CS" number is best for watch parts ?  Also, from one of the ads : "CARBON SPRING STEEL. SIZE IS METRIC 15.00mm X 0.10mm X 304 MM  CS100 FINISH BRIGHT . HARDENED AND TEMPERD TO 480-530VPN" I've no idea about 480-530VPN. Does that mean it needs annealing before working?       Have you seen this video, he shows how to determine where the indents go ?  
    • 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?
