A Type XXI chronograph made for the first time in platinum: this is the special model with which Breguet will be participating in the Geneva Only Watch 2015 auction. Equipped with a flyback function, it offers an immediate reading of the chronograph minutes on the outside of the matt slate grey dial, created especially for the occasion. The chronograph hours are placed at 6 o'clock, together with the date display, the continuous seconds at 9 o'clock, and the day/night indicator is at 3 o'clock. Hands and Arabic numeral hour markers are coated with SuperLuminova for optimal visibility in all lighting conditions. Equipped with a mechanical self-winding movement, calibre 584Q/1, the watch is mounted on an aged calfskin strap, which gives the watch a vintage aura, and is delivered in a case accompanied by a certificate guaranteeing its uniqueness.
