Reviews

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

Traska Seafarer Charcoal

The Traska Seafarer Charcoal is widely praised for its exceptional value, comfortable bracelet with on-the-fly adjustment, and durable construction featuring a proprietary scratch-resistant coating. Owners appreciate its attractive, versatile design and retro aesthetic, with many finding it a perfect daily wearer or beater watch that looks even better in person. Some owners report issues with rotor problems or misalignment, and one user found the 12 o'clock indices crooked. The strap is noted by one owner as feeling cheap, and the 150m water resistance is considered low by one owner for an internal bezel watch. Overall, owners and reviewers rate the Traska Seafarer Charcoal highly for its impressive specifications and build quality at its price point.

From video reviewers

The Traska Seafarer Charcoal's notable strength is its refined finishing, which elevates it from a field watch to a luxury-like piece. A shared weakness is the dim lume, which may be a drawback for those who value nighttime visibility. Reviewers disagree on the watch's build, with one reviewer noting a more substantial build and larger case size, while the other does not mention this feature.

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.
