Tudor MT5402 Caliber Specifications & Guide

The Tudor watch company has more and more gone in the direction of developing and manufacturing in-house movements. This is a natural evolution considering its bigger brother Rolex develops and manufactures all of its movements in-house.

Thanks to Rolex’s expertise and know-how, Tudor can also slowly but surely move in that direction. Using in-house movements is something that is well-regarded in the watch-industry due to the fact that it shows that you are a watch company that means serious business that invests in research, development, and manufacturing.

Tudor’s in-house movements are based on Rolex technology and include techs such as silicon hairspring technology, full balance bridge, and free-sprung Microstella balance wheel.

Since Tudor released its first in-house movement in 2015, together with the new North Flag 91210N. This was the first in-house movement from Tudor, but more would follow soon after.

One of those movements is the MT5402.

MT stands for ”manufacture Tudor” and means that it is a Tudor manufactured movement (in-house).

The MT5402 was introduced in 2018 together with the Heritage Black Bay Fifty-Eight 79030N. In 2016, Tudor released the new in-house version of the Black Bay, however, since the Black Bay Fifty-Eight has a smaller case both in thickness and diameter, Tudor had to develop a new, smaller movement to fit into the case.

The MT5402 replaced the ETA 2824-2 as the movement for Tudor’s smaller watches. The movement is an automatic movement, that includes features like central seconds and a bi-directional winding system.

Just like Rolex, Tudor does not finish its movements to a super high degree. Instead, the movements are meant to look robust and reliable. The Tudor MT5402 is finished in an industrial finish with not a lot of decoration, but when it comes to Tudor and Rolex, the decoration of the movement is not the point. They are instead meant to be reliable workhorses that continue to tick year after year.

  1. I must say I am very impressed with the performance of the MT5402. I have a BB58 that is running on the MT5402 and it is stunningly accurate, and ticks superbly, well within it’s specifications. I can only assume Tudor are going to surpass all expectations, moving forward with their in-house models.
    ‘Well done Tudor’.

    1. Thanks for sharing and yes, you are absolutely correct! Tudor’s in-house movements have proven to perform exceptionally well and this is part of the reason why they decided to introduce the 5-year warranty.Undoubtedly great value for money with that in mind!

  2. Is it characteristic to this movement when fully wound makes a clicking sound and the clutch slips to minimize overwinding to minimize damage to the movement? Keeps accurate time. Is this a problem to worry about? Is the integrity of movement comprised and is in need of repair?

    1. Hi,
      Yes, this is normal. Most automatic watches have some sort of over-winding prevention solution, meaning they will disconnect from the mainspring to prevent overwinding.
      The primary way you would notice if there is an issue with the movement if it is not functioning or performing properly.

  3. Hi,

    Are you aware of which metals/ materials are used within the MT5402 movement itself? I have been searching for a while now, but haven’t found an answer.

    I am interested in the BB 925, but would like to know if there is any gold within the movement?

    Thank you!

    1. Hi,
      Most watch movements, including this one, are made predominantly with steel. A common other material that is used in watch movements is brass.

      This movement does not contain any gold.

  4. I love the movement I do have a Ranger iteration my question is related to the magnetism, let’s say a cellphone, computer, airport, nothing hyper magnetic certainly. Is it safe to use it close to those everyday gadgets ???

    1. Hi,
      when you have a high-quality modern movement like this one, they are designed to withstand everyday magnetism against the things you mention. It is stronger magnets that can cause issues.
      If you are mindful and don’t expose it to unnecessary levels of magnetism, you will be just fine.

  5. Hi,

    I have the BB58 black. Today while i was setting the time, i thought i have pulled the crown out enough, since the second hand was already stopped, turned the crown and there was a click noise, the second hand suddenly ran. I then pulled the crown further, the second hand stopped again and setting the time like normal. I don’t know if i have damaged anything in the movement but right now it keeps the time just fine.

    Do you think if i have damaged anything?

    1. Hi,
      This sounds like the “ghost step/ghost position” which is not completely uncommon for some Tudor watches. It happens when the crown is in between positions. You have not damaged anything and generally, you have no reason to worry.

      Kind regards,
