I received this watch in a lot for repair along with a nice Medana and a Gruen this week and learned something new. Pierce made a lot of their own movements. Not that I’m a purist in the “in house” sense like some. I’d rather have a tried and tested A. Shild or Felsa fitted in an obscure jewellers casel than a well known brand with a glitchy in house calibre that needs constant adjustment or suffers from bad design.

The dial is what caught my attention with the art deco numbers painted with a copper wash on a satin dial. It’s missing a hand and after a quick tear down and soak I discovered the escape wheel is missing the bottom pinion. The finish is better than most with geneva stripes and machined anglage on the bridges so it’s a pleasure to work on.

The movement has a couple scattered numbers that don’t seem in any kind of harmony but I believe it’s a cal 103 for parts purposes. This is another one that needs case work so the torch and silver solder come out and I get to play with fire.

Not huge at 10 1/2 ligne but the case is 32.6 mm making it a good mid size watch. While I look for a new escape wheel I may as well start on the case. Chrome or Nickel  plate over brass. A basic rough sand to take off the scale and a small solder fill for a couple of large pits.

Now a light polish to see where the problem areas are. The next step is a long tarnish removing bath to clean out the holes.

With quite a bit of pitting still evident in the brass the decision is whether to fill with silver solder or grind and polish it out.

Updates as the parts arrive.
