What people say

Owners + reviewers, side by side

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

Longines CONQUEST

Owners widely praise the Longines CONQUEST for its high-quality finishing, excellent value, and versatile design, with many citing the L888.5 movement and 72-hour power reserve as key strengths. The watch is frequently noted for its comfortable bracelet and attractive dials, offering comparable quality to more expensive alternatives. However, several owners and reviewers point out the lack of micro-adjustment on the bracelet clasp as a significant drawback, with some also noting the polished surfaces are prone to micro-scratches and the lume is inconsistent across variants, with only some models featuring lumed hands. On balance, owners and reviewers rate the Longines CONQUEST highly for its impressive finishing and value proposition, particularly its robust movement and versatile wearability.

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.
