An In-House Movement
One of the most important developments is Tudor’s introduction of their very first in-house movement, the MT56XX (the last two digits change per variation). With specs that include a silicon hairspring, COSC-certified accuracy, a 70-hour power reserve (vs 38 hours), and a design that’s close to sister-brand Rolex’s calibers, it was built to last.
This was first launched with their North Flag model, but since Basel 2016, all the Black Bay models come equipped with the movement. The first version of the Black Bay to be offered with the in-house movement is the Black Bay Bronze, and in true fashion, the bronze timepiece also made waves when it was first released.
Over the years, the Tudor Heritage Black Bay has grown into the archetype of vintage-meets-modern done well. With a time-tested design and a movement that’s built to last, it’s worth considering as your next watch.
