Reviews

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

CWC E9 Automatic Diver

Owners widely praise the CWC (Cabot Watch Company) E9 Automatic Diver Watch for its classic dial design, excellent lume, and exceptionally durable PVD-coated case that withstands rough use. Reviewers note the 41mm case wears close to perfectly, with a modest 12mm thickness. One owner suggests replacing the mineral crystal with sapphire to prevent scratches. On balance, owners and reviewers rate the CWC (Cabot Watch Company) E9 Automatic Diver Watch highly for its legible dial and comfortable wearability.

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.
