The Watch
In 1918, aviation took off - and Hamilton was right there, crafting timepieces to keep the new airmail service between the West and East Coasts running on time. That legacy runs deep: Hamilton has maintained close ties with the aviation world ever since, and currently serves as the Official Timekeeper of the Red Bull Air Race World Championship. The Khaki X-Wind Day Date Auto is a natural extension of that heritage - a watch with a bold aviator aesthetic and unmistakable style. Fully Swiss Made, it features a robust, solid stainless steel case measuring 45mm in diameter and 12.80mm thick, making an instant statement on the wrist. The integrated sapphire crystal is built to resist shocks and impacts, and Hamilton has added an anti-reflective coating so you can read the time at a glance, in any light. The graduated bezel helps you place yourself precisely in time. Three crown pushers - two on the right side of the case, one on the left - let you set your watch with ease. Don't wait - let this iconic aviator timepiece win you over.
The Dial
Hamilton's watchmaking manufacture set out to create something truly original - and this timepiece delivers. It features a classic round dial with a rich blue background that invites you to drift away from the everyday. Two two-tone hands (white and gray) display the hours and minutes, while a subtly discreet seconds hand in gray and red keeps you on track. Arabic numerals appear in white at each hour marker, large enough for easy reading, with a 24-hour conversion displayed beneath each one - for example, 2h = 14h. Square-shaped indexes mark the hours alongside a minute track running around the dial's perimeter. A large date window at 9 o'clock displays both the day and the date. Hamilton has noted the movement on the dial at 6 o'clock with the inscription "Khaki X-Wind Automatic", and signs the piece at 12 o'clock in gray capital letters.
The Movement
Powering this watch is a Swiss-made automatic movement with the Hamilton H-30 caliber, renowned for its precision - a must for aviation enthusiasts who never compromise on accuracy. Rest assured, this timepiece will always keep you on time. It boasts an 80-hour power reserve.
The Bracelet
This watch ships with a brown leather strap featuring white stitching and visible rivets, giving the watch a subtle vintage edge. The lug width is 22mm, and it fastens with a tang buckle with a silver-toned clasp.
Water Resistance
This model offers water resistance up to 10 atmospheres, or 100 meters - a truly water-resistant watch. Its sporty character means it's ready to dive into aquatic adventures alongside you. From puddles to the pool, this timepiece handles swimming without a second thought. Showers, baths, and lap swimming are all well within its comfort zone. That said, our Ocarat watch experts want you to know that while this model is water-resistant, it is not designed for diving (professional or recreational) and is sensitive to high-pressure cleaning equipment. We also recommend keeping the crown and pushers dry during immersion.
