Quick TakeThis isn't just a timekeeper; it's a co-pilot with a soul rooted in aviation history. The two-tone case marries rugged stainless steel with the warm glint of yellow gold, echoing vintage cockpit instruments. Its heart, the Caliber L791 flyback chronograph, lets you reset and restart timing with a single push—a feature once vital for pilots. The deep green dial, paired with a matching leather strap, feels both adventurous and refined. It’s a substantial, confident piece for the modern explorer with an old-school spirit.

DescriptionThe timepiece is constructed with a round, 42.00 mm diameter case composed of stainless steel, featuring an 18 karat yellow gold cap 200. The case architecture includes a lug distance of 22 mm, a lug-to-lug dimension of 49.50 mm, and a total thickness of 17.00 mm, contributing to a total weight of 131.0 g. It is equipped with a bi-directional rotating bezel and a screw-in crown, ensuring water resistance up to 10 bar. Both the primary crystal and the transparent case back are fabricated from scratch-resistant sapphire, with the former receiving several layers of anti-reflective coating on both sides. The green dial displays applied Arabic numerals and gilt hands, both treated with Swiss Super-LumiNova® for enhanced legibility.

Powering the instrument is the automatic Caliber L791, a self-winding mechanical movement. This COSC-certified chronometer operates at a frequency of 28,800 vibrations per hour and incorporates a monocrystalline silicon balance-spring, yielding a power reserve of approximately 68 hours. The integrated chronograph complication features a flyback function, operated via a column wheel mechanism. Chronograph indications are presented by a central 60-seconds hand and a 30-minute counter positioned at 3 o'clock. Standard time is displayed with hours, minutes, and a small seconds sub-dial at the 9 o'clock position. The watch is secured to the wrist by a green leather strap, which includes the Longines interchangeable system and a double security folding clasp with a micro-adjustment system.
