Breguet 3817ST Type XXI Flyback SS Grey Dial

The Breguet 3817ST/X2/3ZU Type XXI Flyback in stainless steel stands as a contemporary heir to one of aviation’s most celebrated chronographs. Drawing deeply from the mid-century legacy of the Type XX, originally developed for the French Air Force, the Type XXI merges military utility with modern sophistication. Its 42mm stainless steel case notably houses a high-performance automatic movement, the caliber 584Q/2, featuring both a flyback chronograph and advanced silicon escapement for enhanced precision and longevity. Collectors recognize the hallmark slate grey dial as a distinguished update, complete with luminescent hands and applied hour markers for superb legibility in any conditions. The display caseback, rarely seen on aviation chronographs, showcases Breguet’s fine movement finishing. An integrated flyback function exemplifies the technical prowess and pilot heritage embedded in every detail. Depth rated to 100 meters, it’s as robust as it is refined, representing an elite combination of utility, collectability, and subtle modern aesthetics. As part of the distinguished Type XXI lineage, this reference captures enduring historical significance while delivering contemporary mechanical excellence. Excellent Condition with Breguet box and papers dated 2016.
