Cal. MT5612 is an in-house movement from Tudor, introduced in 2015.

Cal. MT5612 was introduced in 2015 shortly after the first Manufacture Tudor movement, Cal. MT5621. It is quite similar, though without the power reserve indicator. It is a mainstream automatic movement, including common features like central seconds and a conventional date wheel. Being a modern movement, it also has updated 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.

Kenissi produces variants of this movement for other makers:
