What people say

Owners + reviewers, side by side

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

Sugess Seestern Vintage S407 600T

Owners widely praise the Sugess Seestern Vintage S407 600T for its exceptional finishing, bracelet quality, and overall value at its price point. Reviewers and owners alike highlight the watch's fantastic looks and build quality, with one owner noting Seestern did a better job than the original inspiration. Some owners report a slight bezel back play and a clunky clasp, while others have no clasp complaints. Accuracy figures vary, with one owner seeing the watch run 2 seconds slow over 30 hours, and another noting a dial leaning slightly left. The watch measures 40mm wide, 14mm thick, and 48mm lug-to-lug, weighing 86g for the head and 163.4g total with the bracelet, leading some to find it heavy for wrists smaller than 7 inches. One owner questioned if the crown felt wobbly when winding or setting. On balance, owners rate the Sugess Seestern Vintage S407 600T highly for its outstanding build quality and aesthetic appeal relative to its cost.

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.
