Rolex 1040 dead seconds rebuild

This Rolex 1040 came to me with the dead seconds mechanism disabled, the pallets missing, and the pallets post broken off.

Video of the restored mechanism inside!

The owner had found a NOS pallets assembly after an extensive search, and he sent it to me with the watch. Also missing was the very fine U-shaped spring that goes between the two sweep wheels. I made a new mounting post and spring, set up the mechanism, and serviced the watch.
