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.

Fears Onyx (collective Horology)

Owners widely praise the Fears Onyx (collective Horology) for its exquisite glossy black onyx dial, which displays microscopic striations under magnification. Reviewers note its thin case, under 10.5mm, and a balanced sporty-dressy aesthetic. Water resistance is rated at 150m by one source and 100m by another, and the bracelet features on-the-fly micro-adjustment. Some owners find the 39.5mm diameter slightly large for the style, and one source suggests it doesn't represent top value, though it remains competitive. Overall, owners rate the Fears Onyx highly for its unique stone dial and wearability.
