What people say

Owners + reviewers, side by side

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

Venezianico Nereide Ametista

Venezianico Nereide Ametista owners widely praise its striking amethyst-purple dial and proportions, with particular appreciation for the durable tungsten bezel, which is noted as highly resistant to scratches. The bracelet and bezel action also receive consistent positive remarks for their feel and functionality. The watch is frequently highlighted as an excellent choice for a first true dive watch, with its Italian manufacturing and development adding to its appeal. On balance, owners rate the Venezianico Nereide Ametista highly for its distinctive dial and robust, well-executed bezel at its price point.

From video reviewers

The 120-click unidirectional tungsten bezel is a strong point, offering excellent durability. The lume brightness could be improved, as the BGW9 Super-LumiNova is not as bright as some other watches in its class. Reviewers disagree on the standout feature of the watch, with one highlighting the unique dial and the other the sporty yet refined presence of the 42 mm stainless steel case.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.

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.
