Job Number 180089

This is a New York Standard Watch Company 18 size watch, 7 jewels, 5th model.

Here's the dial side with the gears that set and wind in place. Finish and construction on watches like this is crude. You can see machine and tool marks everywhere. Prior repairs don't help either. It can be rough getting things to move together like they should.

This is the ratchet clamp. It integrates the click spring, which is just a flat piece of steel. It could be part of an old mainspring.

Some interesting things here... Note that the lower balance jewel is on a raised platform, rather than integrating into the upper plate as most American 18 size watches do.

The banking pins are set in the lower plate too. They won't be adjustable once the dial in place.

Lastly the tain layout is actually a little odd. The balance pivot point leave the edge of the balance almost at the edge of the movement. And the 4th wheel's position leaves the seconds hand unusually close to the center of the face.

Here is an odd crescent divot in the bottom of the upper plate. I'm not sure what the explanation is for that.

The upper balance jewels, pivot and  cap, are held friction fit by a split in the end of the balance cock. No screws.

I've never seen this before.

Slight dial repair, near the lever as is so often needed...

The outer end of the mainspring on this watch was shot. It really should be replaced. Unfortunately, it's a scarce part. I could not locate one. So I redid the hole in the end of the spring. It will slightly shorten the watch's full runtime, but I think it will hold.
