What people say

Owners + reviewers, side by side

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

Islander Northport 37mm Automatic Watch with Purple Ripple Dial #ISL-291

The Islander Northport 37mm Automatic Watch with Purple Ripple Dial #ISL-291 is widely praised for its looks, build quality, and impressive specifications, including a high-beat Miyota 9015 movement with hacking and hand-winding, sapphire crystal, and 200m water resistance. Owners consider it excellent value, citing the finishing and comfortable fit. One owner notes the bright lume is fleeting. The watch is powered by a Miyota 9015 movement with a 40-hour power reserve. Overall, owners and reviewers rate the Islander Northport 37mm Automatic Watch with Purple Ripple Dial #ISL-291 highly for its exceptional value and robust specifications at its 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.
