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 Superman Steel CMM.10

Owners widely praise the Yema Superman Steel CMM.10 for its refined casework, including polished lug bevels and an elegant crown guard, and its comfortable 39mm x 10.5mm dimensions. The glossy black lacquer dial and bezel insert are noted for adding depth, and the in-house CMM.10 movement is reported to be accurate, with one owner observing a loss of only 2 seconds over 2 days. The scales bracelet is described as gorgeous and nearly invisible on the wrist, though some find its polished center links too flashy. One reviewer flagged the signature bezel lock mechanism as flimsy and inconvenient. The CMM.10 automatic movement offers a 70-hour power reserve and is regulated to within +5/-3 seconds per day. On balance, owners and reviewers rate the Yema Superman Steel CMM.10 highly for its refined finishing and comfortable wearability at its price point.

From video reviewers

The Yema Steel features an in-house movement with a micro-rotor, one of the most beautiful at this price point. The watch's clasp feels a bit thin, which is a notable drawback. Reviewers disagree on the movement's power reserve, with one reviewer noting a 42-hour reserve and the other not mentioning power reserve at all.
