The AChS PILOT collection is a unique combination of the aerobatic aesthetics of the famous AChS-1 and the in-house movement 3603. The prototype of the original shape of the watch case is the geometry of the truncated cone of the anti-shock device of the caliber 3603 itself. The sapphire lens and large Super-LumiNova illuminated indexes and hands ensure excellent readability of the dial in any light.
