Repairing a Nirvana Pocket Watch

[jdrichard]

Set out to clean a Nirvana Pocket Watch and found a few problems. The first was a broken catch on a mainspring. The second was a broken screw in the mainspring arbor, the third was a worn lower balance jewel and its cap jewel as well.

The spring needed to be heated up an the end bent to create a hook. The screw on the arbor broke and I needed to use a lathe to drill it out.

Then I found a worn out lower balance jewel and the cap jewel as well.

Punched it out with my seitz jeweling set and opened up the lip and found a replacement jewel.

Then I found the right cap jewel and pressed it in and reassembled the watch

Put it on my eTimer and regulated it. Not a bad result for an old watch.

Lovely photos and very nice work. When you are gifted with skill and you have the right tools and plenty of old stock, it makes life easier.

This almost worked out extremely well with a small problem. The mainspring is still slipping out of the slot in the wall. Need to investigate.
