Quick TakeForget a stuffy pilot's watch. This is a modern flight instrument with soul. The instant-restart flyback chrono is pure function, ready for anything. Its sunray dial and bronze hands give a nod to history, but the tough ceramic bezel and 68-hour automatic engine inside are all 21st century. It's a substantial, yet wearable piece that feels built for adventure, not just for looking pretty in a hangar. A true tool watch that cleans up nicely.

DescriptionThe timepiece's case is constructed from stainless steel, measuring 42.00 mm in diameter with a lug-to-lug distance of 49.50 mm and a total thickness of 17.00 mm. It features a bi-directional rotating bezel with a ceramic insert and a screw-in crown, contributing to its water resistance of 10 bar. The front is protected by a scratch-resistant sapphire crystal with multi-layered anti-reflective coating on both sides, while the transparent case back also utilizes sapphire crystal. The lug distance is specified at 22 mm, and the total weight of the assembly is 118.6 grams.

The sunray black dial displays time via applied Arabic numerals and PVD Bronze color hands, both treated with Swiss Super-LumiNova® for legibility. Powering the watch is the automatic Caliber L791, a self-winding mechanical movement operating at 28,800 vibrations per hour. It incorporates a monocrystalline silicon balance-spring and offers a power reserve of approximately 68 hours. Standard functions include hours, minutes, and a small seconds sub-dial at 9 o'clock. The integrated flyback chronograph complication is operated via a central 60-second hand and a 30-minute counter positioned at 3 o'clock. The watch is secured by a beige nylon strap equipped with a standard buckle.
