Reviews

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

Baltic Aquascaphe MK2

Owners widely praise the Baltic Aquascaphe MK2 for its refined case design, improved finishing, and value, with many highlighting the added crown guards and Maxi Dial as significant upgrades. Reviewers note the collection's contemporary updates, including a reworked bezel and applied markers, striking a balance between modern practicality and vintage aesthetics. Some owners find the long, straight lugs a drawback, and one owner reported disappointing accuracy averaging +10.5 seconds per day. Overall, owners and reviewers rate the Baltic Aquascaphe MK2 highly for its enhanced design and build quality at its price point.

From video reviewers

The Baltic Aquascaphe MK2 features 3D Super-LumiNova indexes for improved legibility. A notable weakness is the lack of lume brightness. Reviewers disagree on the optimal case size, with one reviewer noting a 41mm stainless steel case is comfortable for everyday wear, while the other mentions 37mm and 39.5mm case sizes are available.

Yema Skin Diver CMM.20

The Yema Skin Diver CMM.20 is lauded for its vintage aesthetic, 39.5mm case size, and well-proportioned handset with sharp indices. Owners praise its textured cream dial, French tool watch elegance, and the smooth winding feel of the in-house CMM.20 micro-rotor movement. The fully brushed bracelet with toolless micro-adjust clasp is considered Yema's best yet. Accuracy readings range from -3/+7 seconds per day to approximately 0 to -10 seconds per day. Some reviewers noted questionable finishing on a prototype's hour hand and a rattly, stamped clasp. The watch's pricing has been questioned by some due to brand QC reputation, and its extended lug-to-lug may challenge smaller wrists. On balance, owners and reviewers appreciate the Yema Skin Diver CMM.20 for its vintage styling and improved bracelet design at its price point.

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.
