The French air force chronograph, in titanium.

The Type 20 was a French military specification of the 1950s for a pilot’s chronograph: black dial, luminous numerals, a rotating bezel and a flyback function, retour en vol, so the timer could be zeroed and restarted without stopping. Breguet supplied the air force and the navy and put a civilian Type XX on sale alongside. The Type XXI of 2004 enlarged the case to 42mm and moved the chronograph minutes to a central hand, which is the feature people buy it for: elapsed time reads at a glance without hunting for a subdial.

In titanium the watch is light for its size, the bracelet is titanium too, and the ruthenium dial is grey rather than black, so the cream luminous numerals sit on it more softly than on the rose gold and black version elsewhere on this page. The small dial at nine carries the running seconds and a day-night disc; the one at three counts chronograph hours.

The dealer’s description is a complete spec list and it matches the photograph: titanium case 42mm by 15.2mm, titanium bracelet with a hidden clasp, rotating bezel, ruthenium dial, date at six, chronograph with central seconds, 30-minute and 12-hour counters and a day-night indicator, calibre 584 Q, 48 hours, sapphire, 100 metres. The Amazon rows carry weight and the model number only. Every figure on this page is the dealer’s or Breguet’s, not measured on this unit.

Whether the watch is new with Breguet’s warranty is not stated in the rows we read; ask, and ask for the box and papers. Every figure here comes from the listing and from Breguet’s published description, not from handling the watch.

This is a regular Amazon listing from an independent dealer, Luxor Watches on the day we read it, with Amazon’s 30-day return window; it is not a Luxury Stores pre-owned unit. The second button opens the live search for Type XXIs in case this one has sold.

Breguet Type XXIs have resold for well under new and close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.
