The new Tudor Movement (in house chrono) - Onlywatch

[Etschell]

"The unique Prince Chronograph carries on this spirit with another incredible first: a brand-new Manufacture Chronograph Calibre entirely developed by TUDOR. The prototype of this calibre, movement “number 0” in the development process, is found inside the TUDOR Prince Chronograph One. The new caliber, MT59XX, features column-wheel construction and meets all TUDOR Manufacture Calibre performance standards.

While The Prince Chronograph One was conceptualized as a celebratory reincarnation of the Big Block Chronograph, it’s thoroughly forward-looking in its execution and represents the best of TUDOR’s core values. To start with, the MT59XX inside the watch is the very movement TUDOR solely developed as a prototype to pave the forward for TUDOR’s modern chronograph calibre. When the “Big Block” Chronograph was produced, the calibre was sourced from third parties with the value proposition to the end user in mind. Now, TUDOR is capable of producing cutting-edge calibres and the Prince Chronograph One is a fitting platform to showcase such an important moment in TUDOR’s history."

So I guess we get a new chronograph soon with this movement. I am wondering how thick the movement is compared to the B-01 and if it may pave the way for a sub 13mm chrono from the brand. would be killer if so.

The current B-01 movement Tudor uses is 7.23mm thick.

The 4130 Rolex movement is 6.50mm thick. I presume the 4131 is similar.
