What people say

Owners + reviewers, side by side

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

Tissot PRX

The Tissot PRX is widely praised for its exceptional finishing, comfortable wearability, and strong value proposition, with owners and reviewers highlighting its luxurious feel for the price. The integrated bracelet, often noted for its shine, finishing, and brushed surfaces with polished edges, is a significant draw, as is the watch's neo-vintage aesthetic and refined dial pattern. The slim case profile, measuring around 10.5mm to 11mm depending on the source, contributes to its comfortable daily wear, and the 100m water resistance is a practical feature. While one owner reported specific issues with a PRX Chronograph's hands and quality control after service, other sources focus on the Powermatic 80's reliable automatic movement and the overall joy of wearing the Tissot PRX. Some find sizing the bracelet challenging due to the lack of a micro-adjustment option.

From video reviewers

The Powermatic 80 movement with its 80-hour power reserve is consistently praised. The lume brightness is noted as a weakness. Reviewers disagree on the suitability of the lug-to-lug fit for smaller wrists.

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.
