C1902 Hamilton 940 18 Size 21 Jewels. Cosmetically Extra Fine Dial & Movement (see Pictures). The Hamilton 940 grade pocket watch was for many years the company's centerpiece watch for the Railway Market.It featured "Extra Fine Ruby Jewels, Patent Motor Barrel, Adjusted to Temperature & Isochronism and 5 Positions, Double Roller Escapement and a Micrometric Regulator". Lids screw on & off correctly. The gold train & jewel setting movement is clean with No discoloration and has no service tool marks. The engine turning decoration pattern is all intact. The gold letter filling is all there with no imperfections. All setting and winding functions work positively and correctly. Dial is exceptional and has 1 hard to see hairline at 1:00. The watch was observed running and carried in a pocket for 24 hours; the last 8 hours resting on a desk. The watch lost 10 seconds during the 24 hour hours. Further regulation of the watch I'm sure would improve it's accuracy even more. I have no history of the watch and assume that it's due for professional serving and adjustments.
