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

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.

Tudor MT56 Family Overview

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.

In 2016, Tudor founded a new movement producer in Geneva known as Kenissi managed by Eric Yvon Pirson (head of Tudor), Jean-Paul Girardin (formerly of Breitling), and Philippe Jacques Dalloz. Two years later, the company constructed a new factory in Le Locle on land owned by Rolex. Chanel invested in Kenissi in 2019, taking a 20% stake in the company. As of 2020, Kenissi produces movements for Tudor, Chanel, Breitling, and Norqain.

Note that Tudor also produces a smaller movement, Cal. MT5402. Although it shares many characteristics with this family of movements, it is different in many details and is considered unrelated.
