What people say

Owners + reviewers, side by side

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

Sternglas Marus

The Sternglas Marus is widely praised for its well-built, heavy feel and excellent bezel action, considered the best in its price range. Despite its 42mm diameter and 52mm lug-to-lug, owners report it fits surprisingly well on slim wrists. A reviewer notes the short seconds hand as a drawback, but highlights the watch as a fun, affordable starting point for a collection, featuring a vibrant Pepsi bezel and an anthracite dial that shifts in appearance, powered by a Miyota 8215 movement for €399. Overall, owners and reviewers rate the Sternglas Marus highly for its robust build and superior bezel at its price point.
