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 Kanton

The Sternglas Kanton is praised for its refined Bauhaus-inspired design, featuring a silver-plated dial and luminous hands and dots for excellent legibility. Owners and reviewers highlight its comfortable 39mm case size, measuring 10mm thick, and the visible STP 1-11 automatic movement through a sapphire crystal case back. Accuracy figures vary, with one source noting +15 seconds per day, while another suggests improved accuracy over previous models. Overall, owners and reviewers rate the Sternglas Kanton highly for its blend of Bauhaus design and Swiss precision at an affordable price point.
