Breguet’s Type XX retour -en-vol chronograph marks its 50th anniversary this year with a new development — the Type XXI — designed to meet the expectations of a generation that looks ahead. The new automatic chronograph Type XXI 3810 retains the military bearing of the original watch Breguet developed for the French naval air arm in the 1950s. The Type XX was ahead of its time, and word soon spread to civilians of its exceptional reliability.
