Waltham 21 jewel grade 645 railroad watch. Lovely watch.

This is a 16 size railroad watch from Waltham made in 1915. Very high quality watch with 21 jewels and full railroad specification. It has just been fully serviced and a new mainspring fitted so it is running strong and keeping excellent time. The watch is stem wind and lever set.
The double sunk white enamel dial is in very good condition as are the hands and the acrylic crystal.
Overall a very nice example in lovely condition working as intended.
