Waltham 21 jewel Vanguard railroad watch. Keeps perfect time!

A 16 size railroad grade pocket watch made by Waltham Watch Co. in 1910 that is today still keeping perfect time. I have run this watch over 3 days and the timekeeping seems to be spot on, remarkable!
The 21 jewel nickel plate model 1908 movement is a development of the earlier model 1899 and in Vanguard spec is one of Waltham's top grade movements. It has a Swiss lever escapement with double roller, Sapphire pallet stones, gold timing screws and a micro-regulator. In addition the watch is fitted with a gold (alloy) centre wheel, gold jewel settings and Waltham's patented "Safety Barrel" which is designed to prevent the rest of the movement from damage should the watch suffer a mainspring breakage.
This watch has just had a full service during which a new mainspring was fitted so it's running strong for the full length of the wind and is keeping really good time. The watch is stem wind and lever set, both functions working smoothly. 
The 3 piece gold filled case with screw on/off covers is in fair condition, whilst there are no dents or dings and the gold is intact apart from the bow the embossed engraved design on the rear cover has worn smooth. The covers remove and replace nicely and both close down square and tight.
The white enamel dial is in excellent condition, please see the photos. The hands are good, as is the acrylic crystal.
Overall a highly collectible railroad watch in really nice condition and working well.
