Khaki Aviation Pilot Day-Date 42 mm Watch H64635140

"La Montre" (The Watch)

Founded in 1892, Hamilton is one of the leading names in global watchmaking. Rooted in American heritage, it combines distinctive design with Swiss technology and uncompromising quality. The brand introduces the new Khaki Aviation Pilot collection, blending adventure and precision with inspiration drawn from aviation history. Reliable and accurate, it is presented here with the H64635140 model, crafted for men with an undeniable sense of style. This watch comes in a case with a modern design and a classic vintage aesthetic. Its round shape suits all wrist sizes, with a 42 mm diameter and a 12.10 mm thickness. Crafted in stainless steel, it is highlighted by a beautiful circular brushed finish on the vertical surfaces of the case sides and lugs. A refined sapphire crystal sits atop the case, offering excellent dial legibility thanks to its double anti-reflective coating. At 3 o'clock, the carefully knurled and protected crown ensures easy adjustment of the hands, date, and day. The transparent caseback delivers a respectable water resistance of 10 ATM.

The Dial

The dial is as elegant as it is functional - perfectly legible and meticulously crafted. It features a rich deep blue color with a subtle sandblasted effect that gives it a matte finish. The bezel ring, in the same hue, is marked by a minute track and rectangular hour markers. This outer ring surrounds a minutes track in oversized Arabic numerals displaying all 60 minutes, alternating with baton indices and a triangle. At the center, a recessed circle highlights the hours in small Arabic numerals printed in white. The ensemble is subtly complemented by bold openworked sword-style hands for hours and minutes, treated with Super-LumiNova® Grade X1 - a high-performance coating that ensures lasting luminosity and clear readability in low-light conditions. The seconds hand is nickel-brushed like the other hands and features an arrowhead tip. The date and day are displayed through the dual display window at 3 o'clock. The finishing touch is the brand logo with the name "Hamilton" below 12 o'clock and the word "Automatic" above 6 o'clock.

The Movement

This model is powered by a Swiss-made automatic movement with an impressive power reserve of 80 hours. It features caliber H-30, based on the ETA C07.621, equipped with 25 jewels and oscillating at a frequency of 21,600 vibrations per hour (3Hz). It boasts a Hamilton-branded rotor and a Nivachron™ hairspring for enhanced resistance to magnetic fields, temperature variations, and shocks. This movement delivers reliable analog three-hand timekeeping with a day and date function.

The Strap

The elegance of this watch carries through to its beautiful silver-toned bracelet. Crafted in stainless steel, it features three rows of links enhanced by an alternating mix of brushed and polished finishes. Comfortable to wear, it sits beautifully on the wrist and stays securely in place thanks to its deployment clasp. Note that this bracelet measures 20 mm in width at the lug.

Water Resistance

This model features a water resistance of 10 atmospheres, or 100 meters. We're talking about a truly water-resistant timepiece! With its sporty spirit, this watch is ready to dive into aquatic adventures alongside you. From puddles to swimming pools, this timekeeper handles water activities without complaint - showering, bathing, and lap swimming are all fair game. That said, our Ocarat watchmaking experts want to be clear: while this model is water-resistant, it is not designed for diving (professional or recreational) and should not be exposed to high-pressure cleaning equipment. We also recommend keeping the crown and pushers dry during immersion.
