Tudor MT5652

Cal. MT5652 is an in-house GMT 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. MT5652 was introduced in 2018 as a GMT member of the mainstream MT5612 family. It has modern features like central seconds, a conventional date wheel, bi-directional winding, hacking seconds, instantaneous date change with crown-based quickset, and a variable-inertia balance with micro-adjustment by screw and silicon balance spring.

Cal MT5612 is finished in a simple “industrial” motif rather than with elaborate anglage or finishing.

Cal. MT5652 was used in the following models:
