The Movement is running well with good aptitude on the Balance Wheel video.

Rotar fitted so the rear side of movement completed

So next time move to the dial side, to reassemble the Day and Date calendar wheels, etc and complete the reassembling of the movement.

Practice of Making a Balance Staff

I spent a bit of time in the workshop today having a practice at making my first watch Balance Staff.

This photograph album and video are relating to my first “practice” of making a Balance Staff out of 1.4mm Blue Steel on my Vintage Telco Watchmakers Lathe.

Link to the photograph album

The Balance Staff is to replace a worn staff on a Model 1908 Waltham Pocket Watch.

Everything went OK until I turned one pivot down to less than 0.2mm, at which time I think I pushed too hard with the hand graver and it broke off.

Don't think I did too bad for my first attempt at making a watch Balance Staff!

Now to practice again!
