What people say

Owners + reviewers, side by side

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

Sinn EZM 3F

Owners widely praise the Sinn EZM 3F for its excellent legibility, robust bead-blasted build, and practical left-hand crown, with some noting its compact, slim wearability and smart appearance on a bracelet. One owner flags minor finishing imperfections and an awkward date window placement, and expresses a desire for tegimented scratch resistance. Overall, owners rate the Sinn EZM 3F highly for its practical mission timer design and compact wearability.

From video reviewers

The Sinn EZM 3F's Ar-Dehumidifying Technology for fogging prevention and temperature resistance is a key strength. Reviewers noted the bracelet lacked on-the-fly micro-adjustment and diver's extensions.

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.
