The Tudor Heritage Black Day 41 ref. 79733N in two tone stainless steel and yellow gold was introduced in 2017, while two-tone watches are coming back with demand, the Heritage Black Bay features “gold-fill” components such as the crown and bezel. Paired with a matching two-tone riveted bracelet, it is inspired by the bracelets used by the firm in the 1950’s and 1960’s. Powered by the firm’s in-house cal. MT5612, is essentially the same movement featured in the Pelagos.
