The dial designs are a frequent point of admiration, with specific appreciation for the white, navy, and gray variants, as well as the orange seconds hand. The watch is considered fairly priced at around $1.5k and is noted for its versatility and "soul."

Yema Navygraf CMM.10

Owners widely report quality control concerns and suspect craftsmanship with the Yema Navygraf, with one user noting crooked text. A reviewer praised the Slim CMM.20 Limited Edition for its stylish, slim profile and classy finishing on a black lacquered enamel dial, though the audible micro-rotor spinning at its price point was a surprise. On balance, the consensus is that while the Yema Navygraf offers a stylish design, potential buyers should be aware of reported quality control issues.
