Breitling Navitimer Cosmonaute "Mercury 7" Special Edition — Rare Aurora Blue Dial — Immaculate UK Full Set Up for purchase is an investment-grade, vault-preserved example of the rare Breitling Navitimer Cosmonaute Special Edition (Ref. AB0210B4/C917/A20BA.1). Released as a historic tribute to astronaut Scott Carpenter’s 1962 Mercury 7 flight, this purist's masterpiece features the legendary 24-hour dial scale, preventing any day/night disorientation in orbit. While the standard black-dial variants are far more common, this example boasts the highly coveted, deeply metallic Aurora Blue dial, beautifully framed by a pristine stainless steel outer coin-edge bezel and a high-contrast white/silver inner rotating slide-rule track. Powered by the spectacular manual-wind Manufacture Calibre B02, this is a true mechanical time capsule for the serious collector. Physical Condition: Vault-Preserved "Safe Queen" To comply strictly with Chrono24's conservative private-seller grading guidelines, this asset is formally listed as "Very Good." Physically, however, the watch is in immaculate, "Like New" condition, showing no visible signs of wear to the naked eye. It has spent its life resting safely on its cushion. The Case & Bezel: The 43mm stainless steel case is entirely unpolished with razor-sharp factory lugs and mirror-finish case flanks. The special-edition stamped "Mercury 7 Carpenter" case back is flawlessly preserved with no tool slips or heavy micro-swirls. The Crystal: The highly domed sapphire crystal features a pristine double-sided anti-reflective coating, entirely free of scratches or outer AR-coating rub marks. The Strap & Buckle: Fitted to its factory-delivered Aurora Blue genuine alligator leather strap (Code: A20BA.1). The premium, large-square scale skin is completely uncreased, and the tan leather underbelly remains bright and clean. Crucially, the adjustment pinholes are perfectly round and unstretched—definitive proof of its lack of wrist time. The high-polish Breitling wing buckle is a brilliant mirror. To give you absolute buying security, the movement has been freshly bench-tested on a professional Weishi 1900 timegrapher. Calibrated strictly to the modern manufacture factory benchmark of a 50.0° lift angle, the Calibre B02 engine returned textbook, showroom-floor performance metrics: Position 1: Dial Up (Flat Desk Orientation) Daily Rate: +7 seconds per day Amplitude: 289° (Exceptional mainspring torque capacity) Beat Error: 0.3ms Position 2: Crown Down (Vertical Wrist Simulation) Daily Rate: +7 seconds per day Amplitude: 260° (Standard vertical friction drop) Beat Error: 0.3ms The Diagnostic Verdict: The watch displays an incredible 0.0 seconds of positional delta change between flat and vertical orientations—a structural rarity that proves the balance wheel is perfectly poised. The running graph traces two razor-sharp, parallel lines of dots with zero structural scatter. The factory lubricants remain beautifully fluid; this movement requires absolutely no service or watchmaker intervention. This is an absolute "Full Set" tracing back to an immaculate British pedigree. All serials (4203033) match flawlessly across the physical case back, the factory packaging labels, and the digital authentication archive. Included in the sale: 1.
