16s Waltham 21 j Cescent St. Wind indicator. Railroad.

Very high quality Waltham railroad watch with wind / power reserve indicator.
Model 1908 nickel plate movement with 21 jewels made in 1915. A very high quality movement with a Swiss lever escapement, Sapphire pallet stones, gold timing screws and a micro-regulator. This movement also has a jewelled  patent safety barrel and a gold (alloy) centre wheel.
The watch has just been fully serviced and fitted with a new mainspring so it's running strong in all positions and keeping excellent time to + a couple of seconds per day.
Railroad spec watch so it's stem wind and lever set.
Gold filled 3 piece case is in fair condition with evidence of age related wear to the embossed rear cover but no dents or dings, and the covers screw on and off as they should.
Very good white enamel dial with no obvious flaws and black enamelled hands to indicate the time all under a very good glass crystal.
Overall a very collectable watch in fine running order and nice cosmetic condition. Daily user?
