Cal. MT5652 is an in-house automatic movement with GMT from Tudor, introduced in 2018.

Cal. MT5652 is a GMT movement with date, and is similar to the date-only Cal. MT5612. It is a mainstream automatic movement, including common features like central seconds, bi-directional winding using a central rotor, hacking seconds, quick date correction, and instant date change. Being a modern design created by Rolex, it uses 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.
