What people say

Owners + reviewers, side by side

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

Maen Skymaster 38 MKIII

The Maen Skymaster 38 MKIII is praised for its refined case, impressive fit and finish, and compact 38mm size, which offers a premium feel with a sharp, legible dial and well-executed applied markers. Reviewers note the sweet winding action and the vintage-inspired brown sunburst dial with dauphine hands and lollipop register pointers. The watch is powered by a manual-wind Sellita SW510Mb movement with a 63-hour power reserve. Accuracy figures vary, with one reviewer reporting +7 seconds per day and another stating a tolerance of +/-15 seconds per day. On balance, owners and reviewers appreciate the Maen Skymaster 38 MKIII for its refined vintage-inspired design and compact dimensions at its price point.

From video reviewers

The 38mm case size is a key strength for the Maen Skymaster 38 MKIII. Reviewers noted the excellent quality-price ratio for a Swiss-made chronograph.

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.
