Breitling 81600 Navitimer Cosmonaute SS / 18K YG Black Dial

The Breitling Navitimer Cosmonaute Ref. 81600 is a compelling revival of the iconic Navitimer line, produced in the mid‑1980s and powered by the venerable Lemania‑based manual wind movement (Caliber 1873), offering approximately 42 hours of power reserve. Its 41 mm stainless steel case paired with an 18 kt gold bezel delivers a striking two‑tone aesthetic that remains highly coveted by collectors. The black dial, rendered with precise chronograph subdials and the classic slide rule bezel, evokes the Navitimer’s aviation heritage while retaining a compact and wearable profile. Measuring roughly 13 mm thick with 22 mm lug width, it balances vintage character with modern presence. Though not a limited edition per se, its production run in the late 1980s and the use of a manual‑wind chronograph movement rooted in aviation history impart a distinct rarity and collector appeal. The Lemania 1873 caliber is celebrated for its reliability and mechanical clarity, aligning this reference with the broader Navitimer legacy. Its understated water resistance (not rated for diving) and mineral crystal preserve the vintage integrity. Offered on a calfskin strap, this reference exemplifies the blend of technical sophistication and timeless design that defines the Navitimer lineage. Excellent Condition with Breitling travel pouch.
