The rich brown dial, with its clear chronograph readouts, is protected by an anti-reflective sapphire crystal, ensuring you have crucial timing data at a glance, whether you're calculating crosswinds or just your coffee break.

DescriptionThe Hamilton Khaki Aviation X-Wind, designated by reference H77916920, is constructed with a substantial 45mm diameter stainless steel case. This case receives a specialized PVD beige coating, imparting a unique aesthetic and additional surface resilience. The vertical dimension, or thickness, of the watch is 14.85mm. Its brown dial is shielded by a highly scratch-resistant sapphire crystal, which features an anti-reflection coating on its surface to maximize clarity and reduce glare. For underwater integrity, the design incorporates a screw-down crown; this contributes to the watch's water resistance capability, rated at 10 bar, translating to 100 meters or 145 psi (328 feet). The presence of an open case back provides a view into the mechanical workings of the movement. Connection to the strap is facilitated by a standard 22mm lug width.

At the heart of this X-Wind Auto Chrono lies the Caliber H-21-Si, an automatic chronograph movement. This advanced caliber is distinguished by its silicon balance spring, a material chosen for its inherent anti-magnetic qualities and its superior stability when subjected to extreme atmospheric conditions, thus promoting consistent timekeeping accuracy. The movement delivers an extended power reserve of 60 hours. Chronograph operations, including starting, stopping, and resetting time measurements, are actuated via dedicated pushers. Time is displayed with chronograph sub-dials. The accompanying strap, identified by reference H6007791021, is fabricated from a durable textile material and fastens with a pin buckle, itself having a width of 22mm, matching the lug width for a seamless integration.
