What people say

Owners + reviewers, side by side

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

Boldr Expedition Enigmath

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.

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.
