Longines Spirit Flyback Automatic Chronograph 42 mm Sunray Black Dial Stainless Steel & Ceramic Bezel Brown Leather Strap [L3.821.4.53.2]

The Longines Spirit Flyback Automatic Chronograph 42 mm [L3.821.4.53.2] is a high-performance pilot’s instrument that exemplifies Longines’ blend of aviation heritage and advanced mechanical engineering. Presented with a refined sunray black dial punctuated by applied Arabic numerals and polished bronze-tone hands treated with Swiss Super-LumiNova® for excellent legibility, this chronograph brings both clarity and style to every measurement.

Equipped with the highly practical flyback chronograph function, this model allows timing to be reset and restarted instantly with a single push — a signature capability born from classic pilot watch requirements. The robust stainless steel case is paired with a bidirectional rotating ceramic bezel and protected by a scratch-resistant sapphire crystal with anti-reflective coating, ensuring durability and clarity under diverse conditions. 

Inside, the watch is powered by a self-winding mechanical movement with flyback chronograph function (Calibre L791) featuring a monocrystalline silicon balance spring for magnetic resistance and reliable performance. With a power reserve of up to 68 hours and COSC chronometer certification, this calibre delivers precise timekeeping combined with chronograph utility. 

Finishing the design is a brown leather strap secured with a double safety folding clasp and micro-adjustment system, providing both comfort and confidence on the wrist. Water resistance to 10 bar (100 metres) adds everyday resilience, making this Spirit Flyback Chronograph a versatile choice for enthusiasts who value performance and elegance.
