One of the biggest developments on this watch, which hides behind the out-of-this-world dial, is the caliber. As previously mentioned, Yema has been doubling down on their collection of in-house calibers that have been taking the market by storm. Designed and manufactured in-house, a process that you can read more about here, these movements are a showcase of the brilliant expertise that the utilitarian and practical brand has tucked up its sleeves. Yema has opted for a variant of their three-hand automatic movement, the CMM 10. The declension used in this Superman is the CMM 11, which features a date window. The spec sheet leaves nothing to be desired in terms of finishing, accuracy, and power reserve. This engine can take on any challenge. Now, you might expect that the process of equipping a standard three-hand automatic with a date is a straightforward and easy process. And yet, the team at Yema would tell you that it was almost as time-consuming as designing a tourbillon. Having heard the whole story about the development of the CMM 11, I have a newfound appreciation for the date window—I will never underestimate it as a complication again.
