X-Wind Day Date Auto Watch H77755533

The Watch
Straight from the world of aviation, the X-Wind Day Date Auto delivers a pilot-inspired look with a blend of classic and flight-specific functions - including hours, minutes, seconds, date/day, and a crosswind drift angle calculator. Swiss Made and built to last, the stainless steel case measures a bold, sporty 45 mm in diameter, ensuring excellent legibility - critical when you're mid-flight. The sapphire crystal offers scratch resistance, while the screw-down caseback reveals the decorated rotor, graduated across 180 degrees for a true aviation aesthetic down to the last detail. Three screw-down crowns complete the look: the right-hand crowns control the crosswind drift angle calculator (hence the name X-Wind), adjusting the inner rotating bezel and its orange-section window, while the left crown sets the time, date, and day.

The Dial
Elegantly black, this dial delivers functionality whether you're cruising in a two-seater or an A380 - from drift angle calculation in the air to hours, minutes, seconds, date, and day on the ground. All markers are oversized and treated with SuperLuminova for guaranteed legibility in any condition, including total darkness. The three large white hands are fully lume-treated for night readability after light exposure. Hours are marked by large white Arabic numerals, equally luminescent. A white minute track runs along the dial's outer edge. The date and day of the week appear in a double window on the left side of the dial - easy to read on a crisp white background.

The Movement
This model is powered by an automatic Swiss-made movement - the Hamilton caliber H-30, 25 jewels, based on an ETA C07.111. It beats at 28,800 vph and delivers an 80-hour power reserve, with hours, minutes, seconds, date, and day displayed via windows at 3 o'clock.

The Strap
The watch ships with a brown leather strap featuring white stitching and exposed rivets for a vintage, masculine, air force-inspired look. It fastens with a silver-tone pin buckle. Lug width: 22 mm. Strap reference: H600.776.103.

Water Resistance
This model offers water resistance to 10 ATM (100 meters) - a genuinely waterproof timepiece. Whether it's a puddle or the pool, this watch handles it all without breaking a sweat. Showers, baths, and casual swimming? No problem. That said, Ocarat's expert watchmakers note that while water-resistant, this model is not suited for professional or recreational diving and should be kept away from high-pressure cleaning equipment. We also recommend against operating the crown or pushers while submerged.
