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

Owners and reviewers widely praise the Baltic Hermétique Tourer for its cohesive vintage-inspired design, appealing layered dials, and legible displays, with particular admiration for its dial depth and indices. The 37mm case is frequently cited as well-proportioned and wearable, complemented by 150m water resistance and impressive value. The recessed crown is a consistent point of discussion, with many finding it fiddly for hand-winding and setting due to its integrated design, though some note this is a stylistic nod to historical waterproof cases. One owner raised a concern about potential marker misalignment on affordable watches. Overall, owners and reviewers rate the Baltic Hermétique Tourer highly for its attractive design and value at the price point.

From video reviewers

The Hermétique Tourer offers strong legibility due to its fully lumed indices. Reviewers noted the lume brightness could be improved.

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.
