Ball Watch Company Trainmaster Eternity. NM2080D-LJ-SL. 

Ball Watches takes a trip into the past with the Ball Trainmaster Eternity watch, a timepiece that remembers the pocket watches of the 19th century that were used for timing the railroad networks. Webb C. Ball, founder of Ball watches, became renowned for outlining the standards of quality and accuracy in all watches used by the railroad, and it is these principles that Ball still lives by today.  

The Ball Trainmaster Eternity watch boasts a finely chiselled 39.5mm stainless steel case which embraces the Swiss made automatic BALL RR1102 movement that can be watched hard at work through the open case back where the oscillating weight twirls with every movement of the wrist. Housed beneath the scratch resistant sapphire crystal glass is a striking silver dial set with 14 luminous micro gas tubes allowing optimal readability even in the dark, a feature that will glow for up to 25 years without requiring recharge. To fasten the timepiece to the wrist, a dark brown crocodile leather strap and stainless steel clasp is added.
