Quick TakeThis isn't just another pilot's watch; it’s a masterclass in proportion. The 37mm case is the sweet spot, delivering a classic feel with modern presence on any wrist. That sunray blue dial is mesmerizing, shifting from deep navy to brilliant azure with a flick of the wrist. Inside, the automatic L888.4 movement is a quiet workhorse, boasting a weekend-proof 72-hour power reserve and a high-tech silicon balance-spring. It’s a robust, go-anywhere companion that looks sharp and keeps running long after others have quit.

DescriptionThe timepiece, reference L3.410.4.93.6, is constructed from stainless steel in a round case shape with a diameter of 37.00 mm. The vertical profile measures 11.70 mm in thickness, with a lug-to-lug distance of 44.80 mm and an inter-lug width of 19 mm. Protecting the dial is a scratch-resistant sapphire crystal engineered with several layers of anti-reflective coating on both its upper and lower surfaces. The dial itself is a sunray blue finish, featuring applied Arabic numerals as hour markers and silvered polished hands. For low-light visibility, Swiss Super-LumiNova® is applied. The total assembly has a weight of 114.7 g and is certified for water resistance up to 10 bar.

Powering the hours, minutes, seconds, and date functions is the Caliber L888.4, a self-winding mechanical movement. This automatic system operates at a frequency of 25,200 vibrations per hour and incorporates a monocrystalline silicon balance-spring for enhanced precision and durability. The movement provides a power reserve of approximately 72 hours. The watch is fitted with a stainless steel bracelet that secures to the wrist via a triple safety folding clasp equipped with a push-piece opening mechanism. The bracelet design incorporates the Longines interchangeable system, facilitating effortless removal and replacement.
