Watch Khaki Aviation Pilot Day-Date 42mm H64635550

The Watch

Hamilton crafts watches that stand out for their exceptional versatility, blending Swiss precision with an American spirit. Founded in 1892, the brand has remained at the forefront of modern watchmaking, delivering high-quality timepieces with designs deeply rooted in its heritage. The Khaki Aviation collection is one of Hamilton's most celebrated lines, drawing inspiration from the pioneering pilots and aviators of the early 20th century. Represented here by the Khaki Aviation Pilot Day-Date H64635550, it strikes a modern attitude with a classic, vintage-inspired aesthetic. The watch features a stunning stainless steel case with a refined brushed finish that perfectly complements its silver tone. Beautifully proportioned, the round case measures 42 mm in diameter and 12.10 mm thick. It is topped by a double anti-reflective sapphire crystal for optimal dial legibility. At 3 o'clock, a well-protected crown with a finely grooved edge ensures effortless function adjustment. The whole is sealed by a case back guaranteeing water resistance to 10 ATM.

The Dial

This exceptional watch is elevated by a unique dial engineered to strike the perfect balance between performance and timeless elegance. Designed with pilots in mind, it features a wide layout with easy-to-read markers and a carefully sandblasted silver finish. Three distinct tiers ensure precise timekeeping: Arabic numeral hour markers occupy the center, surrounded by a finely raised ring marked with large Arabic numerals for the minutes. This ring is complemented by baton indexes at 3, 6, and 9 o'clock, while a triangle replaces the 12 o'clock marker. The outer edge features a minute track and rectangular indexes for each hour. The nickel-plated hour and minute hands are open-worked sword-style, filled with Super-LumiNova® Grade X1 for excellent visibility in low-light conditions. The seconds hand, also nickel-plated and brushed, features a luminescent arrowhead tip. A standout detail is the dual aperture at 3 o'clock, displaying both the day and the date. The brand completes the design with its name and logo below 12 o'clock, and the movement indication above 6 o'clock.

The Movement

This model is powered by a Swiss-made automatic movement - the caliber H-30, based on the ETA C07.621, featuring 25 jewels and beating at 21,600 vph (3 Hz) with a 80-hour power reserve. Equipped with a Nivachron™ hairspring for enhanced resistance to magnetic fields and temperature variations, it also features a Hamilton-branded rotor. This movement delivers three-hand timekeeping with a day-date function.

The Strap

The strap on this watch brings a touch of elegance to your wrist while seamlessly complementing any outfit. Crafted in light brown calf leather with tone-on-tone stitching, it is elevated by the iconic "H" with wings emblem - the signature of the collection. Unique in every way, it measures 20 mm in width and fastens with a tang buckle for a secure and comfortable fit.

Water Resistance

With a water resistance of 10 atmospheres, equivalent to 100 meters, this is a genuinely water-resistant watch. It's ready to join you in the water - from puddles to the pool. Showering, bathing, and recreational swimming are no problem. That said, our Ocarat watchmaking experts note that while this model is water-resistant, it is not designed for diving (professional or otherwise) and should be kept away from high-pressure cleaning equipment. We also recommend avoiding crown or pusher operation while the watch is submerged.
