What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Islander Automatic Dive Watch with Bracelet, Double-Domed AR Sapphire Crystal, and Embossed Ceramic Bezel Insert #ISL-18

Islander Automatic Dive Watch with Bracelet, Double-Domed AR Sapphire Crystal, and Embossed Ceramic Bezel Insert #ISL-18 owners praise its $300 value, noting the double-domed AR sapphire crystal and embossed ceramic bezel. The 43mm size is appreciated, and the NH36 movement offers hand-winding and hacking. On balance, owners rate the Islander Automatic Dive Watch with Bracelet, Double-Domed AR Sapphire Crystal, and Embossed Ceramic Bezel Insert #ISL-18 highly for its substantial feel and feature set at the price point.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.

From video reviewers

The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
