Details & Specifications
Description:
The Breguet Type XXI reference 3810ST/92/9ZU brings the brand's celebrated aviation chronograph heritage into a modern 42mm stainless steel case, tracing its lineage back to the Type 20 chronographs developed for the French Air Force in the 1950s. The brown dial is set with luminous Arabic numerals and hands, complemented by a central flyback minute counter with an arrowhead tip that circles the chronograph seconds and minutes scale, alongside a day/night indicator, a 12-hour totalizer, and a date window at 6 o'clock. A graduated rotating bezel and a screw-locked crown reinforce the watch's tool-watch heritage, while a sapphire caseback reveals the automatic movement inside. Powered by the self-winding Calibre 584Q, fitted with a silicon balance spring, the watch is water-resistant to 100m.
