Sometimes the bench gets a different type of repair request. In this case it is a GM dashboard that has failed. All of the stepper motors are to be replaced and I have to inspect and repair any cold joints. Notice the dark areas which certainly help pinpoint an area to inspect.

my repair is done and just dropped it off to the owner. It turns out those joints on the backside of the board were not the issue. rather it was bank of surface mounted resistor that had micros-fractures in the soldering.  Had to use a 20x loupe the see them but they were there.  

The more you see modern technology the more you appreciate the work and design that went into vintage horology :)

      Omega cal. 565 - low amplitude

      By JohnR725 · Posted

      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?

      Hi all

      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.
