Quick TakeThis isn't just a watch; it's a co-pilot for your life's adventures. That sunray blue dial, paired with bronze-toned hands, has a magnetic pull. But the real magic is the flyback chronograph. One press and you're timing the next leg of your journey without missing a beat. It feels substantial on the wrist, a solid 178-gram tool, yet the view through the transparent back at the L791 movement is pure mechanical poetry. With its 68-hour power reserve, it's ready to go whenever you are. This is a serious piece of kit that doesn't take itself too seriously.

DescriptionThe timepiece's architecture is based on a round stainless steel case with a diameter of 42.00 mm and a thickness of 17.00 mm. The lug-to-lug measurement is 49.50 mm, with an inner lug distance of 22 mm. The case is fitted with a bi-directional rotating bezel incorporating a ceramic insert. Protection for the dial is provided by a scratch-resistant sapphire crystal, which features multiple anti-reflective layers on both its upper and lower surfaces. The case back is transparent, also utilizing a sapphire crystal, and integrates a screw-in crown to ensure water resistance up to 10 bar. The total weight of the assembly is 178.3 grams. The sunray blue dial displays time with applied Arabic numerals and PVD Bronze color hands, all treated with Swiss Super-LumiNova® for visibility.

At its core operates the automatic Caliber L791, a self-winding mechanical movement with a frequency of 28,800 vibrations per hour. This movement is equipped with a monocrystalline silicon balance-spring and provides a power reserve of approximately 68 hours. Standard timekeeping functions include hours, minutes, and a small seconds sub-dial positioned at 9 o'clock. The integrated chronograph complication features a flyback function, operated via pushers. The chronograph display consists of a central 60-second hand and a 30-minute counter located at the 3 o'clock position. The watch is secured to the wrist by a stainless steel bracelet featuring a double safety folding clasp with a push-piece opening mechanism and the Longines interchangeable system for strap versatility.
