Tudor MT5402

Cal. MT5402 is an in-house movement from Tudor, introduced in 2018.

Tudor traditionally used movements from major manufacturers, chiefly ETA in modern times, as a differentiator from parent company Rolex. Beginning in 2015, the company began producing a line of “Manufacture Tudor” movements for certain models, beginning with Cal. MT5621. These are based on Rolex technology, and include that company's silicon hairspring technology, full balance bridge and free-sprung Microstella balance wheel.

Cal. MT5402 was introduced in 2018 and is smaller than previous Manufacture Tudor movements at 26.0 mm diameter to better replace the ETA 2824-2 in smaller watches. It is a mainstream automatic movement, including common features like central seconds and a bi-directional winding system.

Cal MT5402 is finished in a simple “industrial” motif rather than with elaborate anglage or finishing.

Cal. MT5402 was used in the following models:

• Tudor Heritage Black Bay Fifty-Eight (2018-present)
