And when Tudor resolved to introduce its own dedicated chronograph movement, it worked not with Rolex but with Breitling, adopting that brand’s Caliber B01 as the base for Tudor Caliber MT5813, which made its auspicious debut in 2017’s Heritage Black Bay Chronograph. (The partnership is mutually beneficial; Breitling uses the stripped-down, sans-chronograph version, the MT5612, as a base movement for its Heritage Superocean model.)
