Tritium Illumination & Dual Sapphire Crystals

Ball’s Trainmaster Roman automatic has elements of ruggedness and pure sophistication. The stainless steel case and band are thick and prominent, creating a durable feel on the wrist. However, the dial is much more whimsical. Roman numerals and vintage, grandfather clock–style hands meet tritium-illumination in the hands and pips. The result is both tastefully old school and new-wave. Ball’s RR1102 movement is the engine on this 41-millimeter bad boy. Its 25 jewels are visible through the sapphire display caseback. As for water resistance, the watch has a rating of 5 ATMs, so it’s okay to spill on it or run it under a faucet.
