What people say

Owners + reviewers, side by side

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

William Wood Fire Watch

William Wood Fire Watch owners praise its conversational value and attractive design, noting its fun graphics and comfortable straps. Reviewers highlight the unique British fire exit sign inspiration and playful details. However, the small day and date indicators are difficult to read, and one owner points out that the day wheel windows do not align to show seven days. The William Wood Fire Watch is priced at $1,903 USD and uses a Sellita SW220 automatic movement with a 41-hour power reserve. On balance, owners and reviewers rate the William Wood Fire Watch highly for its unique design and conversational appeal at its price point.

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.
