What people say

Owners + reviewers, side by side

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

Spinnaker Hull Titanium Bronze

The Spinnaker Hull Titanium Bronze is a sold-out limited edition that has garnered significant interest, with one owner noting its titanium case stands out with a white strap. Owners are split on the watch's value, with one finding it a good purchase at $125 and another questioning the strap's suitability for its 100M water resistance. Some reviewers flag the VK73 movement's limited 60-minute chronograph and a big date window obscured by the chronograph hand, while others praise the handsome design with a textured sandwich dial and comfortable wearability. Lume is described as non-existent by one source. Overall, owners and reviewers are divided on the Spinnaker Hull Titanium Bronze, with praise for its design and wearability tempered by criticism of its movement execution and strap.

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.
