It inherits the general lines, as well as the dial and domed crystal, from the very first TUDOR diving watches. It also features the particularly prominent winding crown known as Big Crown. Also, it borrows the characteristic angular hands, known as snowflake.
The characteristic element of the Heritage Black Bay Bronze is an imposing bronze case, 43 mm in diameter. The choice of this metal, a high-performance aluminium bronze alloy, guarantees the development of a subtle and unique patina. A combination of elegant chocolate-brown dial and bezel – a first for TUDOR – with golden and beige accents, completes the model's look.
Tudor really sealed the success of its re-establishment by introducing in-house Caliber MT5621. This was the first in-house mechanical development in the brand’s history. Conceived with efficient bidirectional automatic winding and a 70-hour power reserve, this movement also contains an ultra-modern element: a silicon balance spring. It is also officially certified as having attained chronometer precision.
