What people say

Owners + reviewers, side by side

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

Baltic Hermétique Tourer Bronze

The Baltic Hermétique Tourer Bronze is widely praised for its vintage-inspired aesthetic, featuring a bronze case and a smoked dial that develops a unique patina. Owners and reviewers highlight its comfortable wearability, noting the slim case profile and manageable lug-to-lug distance. The watch offers 150 meters of water resistance, supported by a recessed crown that contributes to its silhouette, though some find it tricky to grip. It is powered by the Miyota 9039 movement, which provides a 42-hour power reserve and a smooth seconds hand sweep, with accuracy reported between -10/+30 seconds per day. Overall, the Baltic Hermétique Tourer Bronze is highly regarded for its attractive design and comfortable wearability at its price point.

From video reviewers

The watch's slim profile and comfortable fit are consistently praised. Reviewers note the bronze case develops a unique patina. No shared weaknesses were identified.

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.
