Quick TakeThis is a machine with soul, a throwback to the golden age of aviation wrapped in modern tech. The flyback function is pure tactile joy—one press and you're timing the next leg of your journey. Its sunray dial captures the light, a dynamic contrast to the warm bronze hands and the robust feel of the steel case. This isn't a watch that just sits there; it begs to be used, to be part of an adventure. It’s a substantial, confident piece that feels engineered, not just designed.

DescriptionThe instrument designated by reference L3.821.4.53.2 features a round case architecture composed of stainless steel, measuring 42.00 mm in diameter and 17.00 mm in thickness. The lug distance is specified at 22 mm, with a total lug-to-lug dimension of 49.50 mm. A key functional element is the bi-directional rotating bezel, which is fitted with a ceramic insert. Water resistance is rated to 10 bar, ensured in part by a screw-in crown. The case is sealed by a transparent case back with sapphire crystal, matching the scratch-resistant sapphire crystal on the front, which has several layers of anti-reflective coating on both sides. The total weight of the assembly is 127.7 g. The dial presents a sunray black finish, with time indicated by applied Arabic numerals and PVD Bronze color hands, all treated with Swiss Super-LumiNova®.

At its core is the Caliber L791, a self-winding mechanical movement operating at a frequency of 28,800 vibrations per hour. This movement integrates a monocrystalline silicon balance-spring and delivers a power reserve of up to 68 hours. The primary complication is a flyback chronograph, with functions displayed by a central 60-seconds hand and a 30-minute counter subdial at the 3 o'clock position. Standard timekeeping includes hours, minutes, and a small seconds register at 9 o'clock. The watch is furnished with a brown leather strap featuring the Longines interchangeable system, which fastens with a double security folding clasp that includes a micro-adjustment system.
