Tudor in-house Caliber MT5652 Specifications
In the work towards establishing itself as a major player in the luxury watch industry, and to differentiate itself from its bigger brother Rolex, Tudor has, since 2015 released a number of in-house calibers.
The first in-house caliber was launched in 2015, and it’s safe to say that the brand has only increased in popularity in recent years. Building and developing in-house movements is considered an important effort for any watch company that is serious about its craft.
Developing in-house movements takes time and effort, and demands lots of resources. But at the same time, it gives the watches a greater value proposition to your customers as it makes the brand go from a watch assembler to a watch manufacturer. It goes to show that the brand goes above and beyond to invest resources into the watch industry, and developing into its own craft. It also gives the brand greater control and more independence. Making your own in-house movement as a manufacturer means going from a watch assembler to a watch manufacturer.
In this article, we are going to go into detail about the Tudor in-house caliber MT5652.

The problem here is that even the best watchmakers in the US are unable to secure the Microstella Balancing Wrench / Regulating Tool for Tudor’s Caliber MT5652.
My watchmaker theorized that Tudor wants to require all owners of their calibers to be forced to only work with Tudor on servicing issues. Unlike with Rolex which most watchmakers have the Microstella Balancing Wrench / Regulating Tool for adjustments and thus in a couple or few visits you can get your Rolex to within a <+1 accuracy, at least my watchmaker always has with my watches I wear 24/7.
Where can my professional watchmaker source the Microstella Balancing Wrench / Regulating Tool for the Caliber MT5652?
Hi,
Thanks for sharing. Yes, that is certainly a logical and perfectly reasonable theory.
I would say that the best shot would be to find a third-party tool on places like Aliexpress or Alibaba. Finding an original one would likely be extremely difficult as Tudor does not sell tools to non-authorized retailers.
Kind regards,
