📖 About This Reference

The Breguet Type XXI, reference 3817, is a notable iteration within the Type XX family, distinguished by its flyback chronograph function and a central minute counter. This model represents a contemporary interpretation of Breguet's historical pilot's chronographs, offering a refined aesthetic while retaining the core functionality expected of the series. Its design cues and technical specifications position it as a significant piece for collectors interested in modern horology with a heritage connection. This timepiece features a stainless steel case measuring 42 mm in diameter, housing the automatic Breguet calibre 584Q/2. This movement provides a power reserve of 48 hours and is known for its robust construction, incorporating a cam-switched, horizontally coupled chronograph mechanism. The watch is fitted with a sapphire crystal and offers water resistance up to 100 meters, making it suitable for daily wear. The brown dial complements the case material and strap choice. For collectors, the reference 3817 appeals to those who appreciate a blend of traditional chronograph mechanics with modern finishing and wearability. Its connection to the Lemania 1340/Omega 1040 ebauche provides an interesting historical lineage for movement enthusiasts. The flyback complication enhances its utility, allowing for rapid resetting and restarting of the chronograph function, a feature often valued in timing instruments.

Questions on the XXI 3815 and 3817 for those that actually have them.
Years ago I had a XX Transatlantique and now looking to buy another type XX/ XXI. I haven't found a good answer about the sub dial at 3 o'clock. Some of the reviews say it is a hour counter for the chrono and others say it is to tell day/night time. I have used the sun for that. On the 3815 I can se
