Wolbrook Skindiver AutomaticvsYema Wristmaster Slim CMM.20

The Wolbrook Skindiver Automatic is widely praised for its attractive vintage aesthetic, comfortable wearability, and legible dial, with many owners highlighting its quality build and value under $500. Owners often commend the Beads of Rice bracelet and tropic strap, the box sapphire crystal, and the overall solid feel that suggests nothing is cheap. Specific praise is given to its lume, which some find lasts well and is great, and its accuracy, with one owner noting exceptional performance. However, some find the finishing merely fine, not exceptional, and note issues with the push-pull crown lacking a positive lock or being noisy. The 20mm strap width and drilled lugs that don't fit all spring bars are also mentioned as potential drawbacks. The Miyota 8315 movement, while preferred over the 8215, is described by one owner as noisy, and the non-transferable warranty policy is a concern for some.

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.
