Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Squale 1545 for its solid build quality, attractive appearance, and excellent value, with many highlighting its impressive tuxedo black lacquer dial and exceptionally bright lume. Some owners note the clasp as a point of dissatisfaction, a common issue across various price points, and one reviewer points out minor flaws on the steel bracelet including soft end links and a clasp that scratches the bracelet. The Squale 1545 is considered a reliable and versatile everyday watch with historical design precedent. Overall, owners and reviewers rate the Squale 1545 highly for its impressive finishing and value at its price point.
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.
The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
