Quick TakeStrap this on, and you're not just wearing a watch; you've got a co-pilot forged for the modern adventurer who appreciates mechanical prowess. The Hamilton Khaki Aviation X-Wind Auto Chrono isn't shy, with its assertive 45mm stainless steel physique and a captivating blue dial that mirrors the endless sky. Inside, the H-21-Si automatic movement is a marvel, boasting a silicon balance spring for unwavering accuracy and a hefty 60-hour power reserve – because your expeditions don’t stick to a 9-to-5. It’s more than ready for a splash, thanks to 100-meter water resistance and a screw-down crown. From the tactile textile strap to the clear view of the sapphire crystal, every element feels purposeful. This isn't just about telling time; it's about mastering it, with a chronograph at your fingertips and an open case back revealing the heart of this airborne beast. It’s a statement piece that screams capability without saying a word.

DescriptionThis timepiece incorporates the Caliber H-21-Si, an automatic chronograph movement known for its precision and durability, largely due to the inclusion of a silicon balance spring which offers superior resistance to magnetism and extreme atmospheric variations. Operational integrity is maintained by a 60-hour power reserve. The robust stainless steel case measures 45mm in diameter and has a thickness of 14.85mm, ensuring a significant presence on the wrist. Protection for the blue dial is provided by a sapphire crystal, enhanced with an anti-reflection coating for optimal legibility under various lighting conditions. Water resistance is rated at 10 bar, equivalent to 100 meters or 145 psi (328 feet), a capability supported by the screw-down crown feature, which enhances the case's seal against moisture ingress.

Further detailing the watch's construction, an open case back allows visual appreciation of the intricate movement within. The lug width is a standard 22mm, accommodating the supplied textile strap. This strap, reference H6007791011, is secured with a pin buckle that matches the lug width at 22mm, ensuring a consistent and secure fit. The H-21-Si movement facilitates timekeeping and measurement through its chronograph functions, typically displayed via sub-dials positioned at 6, 9, and/or 12 o’clock, with start/stop and reset pushers located on the case side. The overall design and material choices underscore its position within the Khaki Aviation collection, reflecting a blend of rugged functionality and sophisticated mechanical engineering, currently part of Hamilton's active collection.
