Reviews

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 is considered a positive for a modern mechanical chronograph. Reviewers highlight its clean dial, sharp legibility, and well-executed applied markers, with one noting a brown sunburst dial evoking vintage tropical effects. The winding action is described as sweet, and the watch is powered by a Sellita SW510Mb manual-wind movement. Accuracy figures vary, with one source reporting an average of +7 seconds per day and another stating a tolerance of +/-15 seconds per day, and both note a 63-hour power reserve. Overall, reviewers rate the Maen Skymaster 38 MKIII highly for its vintage-inspired design and premium feel 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.
