In the watchmaking industry, if you want to be taken seriously, you need to develop and manufacture your own in-house calibers.

The Tudor Caliber MT5612 is a fully in-house developed movement. The ”MT” stands for ”Manufacture Tudor” and tells us that it is in an in-house movement. It was released by Tudor in 2015.

The caliber has a power reserve of 70 hours which is rather impressive.Tudor-caliber-MT5612

At its core, it’s a standard time movement with hours, minutes, and seconds, but it also has a date function positioned at 3 o’clock.

The movement beats at a frequency of 28,800 beats per hour (4 Hz). This is the same frequency that its bigger brother Rolex has used for its in-house movements for many decades. The movement is also COSC certified. As you would expect, the Tudor Caliber MT5612 has a bidirectional rotating bezel that powers the watch. The movement is, in turn, regulated by a variable inertia oscillator with silicon balance spring. Tudor has also used a traversing bridge on both sides of the spring in order to improve the caliber’s resistance to shocks. The silicon balance spring also improves the caliber’s anti-magnetic characteristics.Tudor MT5612

The difference between the Tudor Caliber MT5612 and the MT5602 is the fact that the latter does not have a date function, and has one less jewel.
