Quick TakeThis isn't just a watch; it's a co-pilot. Feather-light on the wrist thanks to its titanium body, you almost forget it's there—until you need it. That's when the flyback chronograph snaps to attention, resetting with a single push, ready for your next command without missing a beat. Gilt hands gleam against the dark, sunray anthracite dial, catching the light and your eye. It’s a modern tool with an old-school aviation soul, tough enough for any adventure but with a sophisticated mechanical heart beating inside, visible for all to admire.

DescriptionThe timepiece is constructed with a round case architecture composed of Grade 5 titanium, featuring a bi-directional rotating bezel with an inlaid black ceramic insert. The primary case dimensions are a diameter of 42.00 mm, a lug-to-lug distance of 49.50 mm, and a total thickness of 17.00 mm, with an inter-lug width of 22 mm. Protection for the dial is provided by a scratch-resistant sapphire crystal, which incorporates several layers of anti-reflective coating on both its upper and lower surfaces. The case back is also fabricated from transparent sapphire crystal, allowing for an unobstructed view of the internal mechanism. Water resistance is rated to 10 bar, a specification supported by the inclusion of a screw-in crown. The total weight of the assembly is 93.6 grams.

The dial is presented in an anthracite color, featuring applied Arabic numerals as hour markers and gilt hands for the primary time indication. Legibility in diminished ambient light is augmented by the application of Swiss Super-LumiNova®. Powering the instrument is the Caliber L791, a self-winding mechanical movement. This automatic caliber operates at a frequency of 28,800 vibrations per hour and provides a power reserve of approximately 68 hours, due in part to its monocrystalline silicon balance-spring. Standard functions include the display of hours, minutes, and a small seconds sub-dial positioned at 9 o'clock. The chronograph complication is of the flyback variety, operated via pushers and displaying elapsed time through a central 60-seconds hand and a 30-minute counter located at the 3 o'clock position. The watch is affixed to the wrist with a black nylon strap equipped with a titanium buckle.
