What people say

Owners + reviewers, side by side

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

Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition

The Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition is praised for its attractive emerald green sunburst dial with gold accents and its comfortable wearability. Owners note the dial looks gorgeous in the right light, and some find it fits better than other models. The watch features a 40mm steel case, a domed sapphire crystal, and 300m water resistance, powered by the 6R55 movement with a 72-hour power reserve. However, some find the watch wears top-heavy due to its density and case design, and the bracelet clasp is criticized for stamped parts and limited micro-adjustment. The retail price of €1,700 is considered high by some, with sales recommended. Overall, owners and reviewers appreciate the dial's beauty and the watch's comfortable fit, despite some reservations about its weight distribution and bracelet clasp.

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.
