What people say

Owners + reviewers, side by side

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

Marathon Jeep Willys SSGPM

The Marathon Jeep Willys SSGPM is praised for its handsome, retro design and attractive, clean dials with great hands. Owners note the case is nicely shaped and offers good value at $650 USD. However, some find the lugs extend far on smaller wrists, and the corporate Jeep logo detracts from the dial's appeal for some. The leather strap may need replacement with regular wear. Overall, owners and reviewers rate the Marathon Jeep Willys SSGPM highly for its retro design and value, despite some reservations about the Jeep branding 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.
