{{wst>image_cr|Tudor|MT5402}}

**Cal. MT5641** is an [[in-house]] [[big date]] movement from [[Tudor]], introduced in [[2018]].

===== History =====
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. These are based on Rolex technology, and include that company's [[silicon]] [[hairspring]] technology, full [[balance bridge]] and [[free-sprung]] [[Microstella]] [[balance wheel]].

Cal. MT5641 features a [[big date]] window at 12 00 and [[small seconds]] at 6 00. Cal MT5641 is finished in a simple "industrial" motif rather than with elaborate [[anglage]] or [[finishing]].

This movement features modern technology, including [[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.

===== Applications =====
Cal. MT5641 was used in the following models:
