The A-15 Pilot Watch is inspired by the 1944 Military Issue A-15 Elapsed Time Watch and incorporates unique features of the original. A stainless steel case with distinctive black dial features two rotating inner discs operated by two crowns. The 2H crown rotates elapsed time while the 4H crown indicates dual time. The unique design of this timepiece, as well as its functional features, are made more authentic by the fine 21-jewel automatic movement with a 42-hour power reserve. The subtle topstitched brown leather strap completes the look. Sapphire crystal with anti-reflective coating. Water resistance to 30 metres.
