The watch offers a retro motorsport aesthetic with a quality finish and well-chosen movements at an affordable price. Reviewers did not agree on any specific weaknesses.

Yema Wristmaster Slim CMM.20

The Yema Wristmaster Slim CMM.20 is widely praised for its compelling integrated bracelet design and comfortable 39mm wearability. Reviewers highlight its impressive value, featuring an in-house CMM.20 micro-rotor movement with a 70-hour power reserve, adjusted to -3/+7 seconds per day, all within a slim 9mm case. Some note the domed sapphire crystal can produce glare and the dial text is quite small. On balance, reviewers rate the Yema Wristmaster Slim CMM.20 highly for its integrated design and value proposition with a micro-rotor movement.
