Possibly the oldest watch I have taken apart so far. The totally amazing thing about this is the pristine shape of the movement. I am lead to believe that the watch has been to Bienne at one stage for a change of movement. The owner had never heard that his father ever shipped it out, nor his grandfather, so I guess the watch has been kept is a dry safe place and generally been well taken care of. Still the crystal was screaming for a shine, and a bit of brass polish fixed that easily!

The watch before and after the cleaning and polishing work.

It is a bit unfair, because the right picture shows the dial without the crystal. Believe me, the crystal is sharp now!
