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 Slim CMM.20

Owners and reviewers widely praise the Yema Skin Diver Slim CMM.20 for its balanced 39mm case, vintage aesthetic, and unique champagne dial. The proprietary CMM.20 micro-rotor movement is a notable feature, though some owners report potential QC issues including erratic timegrapher readings and second-hand stutter. The lume is described as subdued, and while some find the "dragon scale" bracelet beautiful, others consider it generic. The price point is a hurdle for some, and the stamped clasp quality is considered subpar by one reviewer, with a gap noted by an owner. The lack of hacking seconds is flagged as a drawback at its price. Overall, owners and reviewers rate the Yema Skin Diver Slim CMM.20 highly for its vintage charm and balanced wearability.
