Duometre à Chronographe (First Generation)

Introduced in 2007, the Duometre à Chronographe debuted the Dual-Wing concept, using separate barrels and gear trains for timekeeping and the chronograph while sharing one regulating organ. It offered an original solution to preserving precision when a complication is running.
