Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Phoibos Narwhal is praised for its captivating aventurine and Howlite dials, and its 38mm case is noted to wear well on smaller wrists, with one owner comparing its profile to a vintage Zenith El Primero. Some owners appreciate the brand's quality for the price, with one describing the case shape as resembling an integrated bracelet. However, criticisms include misaligned markers and a tilted date window, with one owner finding the hands to be too thick. The watch is considered by some to be overpriced at $480, with a slabby design and difficult-to-size bracelet links. Opinions are split on the 38mm size, with some finding it wears larger than expected, and the brand's logo is polarizing. Overall, owners rate the Phoibos Narwhal highly for its unique dial options and distinctive case design at its price point, despite some concerns regarding finishing consistency.
The unique stone dial is a significant strength. The bracelet's refinement is a weakness. Reviewers disagree on the dial's appeal, with one highlighting its sunburst effect and applied indices, while another focuses on the natural stone variation.
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.
