Type XXI

High-frequency Breguet engineering. Mint condition. Full set. Breguet Type XXI Flyback Chronograph Ref. 3810ST • Full Set One of the most technically interesting watches from Breguet’s Type XX collection, the Type XXI combines the historic aviation-inspired design with a high-frequency 10Hz movement, flyback chronograph and dual-time functionality. This example has spent virtually its entire life stored in a safe and presents in exceptional condition. Watch Snapshot: • Reference: 3810ST • Condition: Mint / Like New • Full Set with box and papers • Stainless steel case • 44mm case diameter • Grey dial • Flyback chronograph • High-frequency 10Hz automatic movement • Second time-zone display • Date display • Bidirectional rotating bezel • Brand-new leather strap • Original Breguet deployant clasp Condition Notes: Exceptional mint, like-new condition. The watch has spent virtually its entire life stored in a safe and shows accordingly, with a very clean case, bezel, dial and crystal. It is currently fitted with a brand-new leather strap and is accompanied by its full original set. Why This Piece: The Type XXI is not simply another Breguet chronograph. Its 10Hz movement operates at an unusually high frequency of 72,000 vibrations per hour, allowing the central chronograph seconds hand to complete a full revolution every 30 seconds. Combined with the flyback function and second time zone, it represents a distinctly technical side of Breguet that you don't see in many of the manufacture's watches. For a Type XXI, finding an example this well preserved with its full set and a fresh strap makes this one particularly compelling. Private Sales • Collection Sourcing • Acquisition Services
