amilton expands its Khaki Aviation Pilot Pioneer line with two new references of the Mechanical Chronograph 40mm, a watch inspired by the rugged timepieces supplied to the British Royal Air Force in the 1970s.

Featuring a striking Aviation Blue sunray dial, cloudy-white hands, and Arabic numerals enhanced with Grade X1 Super-LumiNova®, this model ensures exceptional legibility in all conditions.

The brushed case contrasts with polished pushers and crown, while the vegetable-tanned brown leather strap or stainless-steel mesh bracelet offers versatile styling. A box-shaped sapphire crystal adds retro flair while the double anti-reflective coating gives a modern twist.

Hamilton’s handwinding movement H-51-si with 60h power reserve and silicon balance spring deliver precision and unmatched resistance to magnetism, shocks, and aging.
