====== Tudor MT5621 ======

{{wst>image_cr|Tudor|MT5621}}

**Cal. MT5621** is the first [[in-house]] movement from [[Tudor]], introduced in [[2015]].

===== 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. MT5621 was the first Manufacture Tudor movement and features a [[power reserve indicator]] at 9 00. Most other features are more common, including [[central seconds]], and a conventional [[date wheel]]. The specs of Cal. MT5621 are identical to the smaller [[Rolex 3255]] in the [[Rolex Day-Date 40]] introduced at [[Baselworld]] in [[2015]]. Cal MT5621 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.
