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.

HELM Miyako

HELM Miyako owners widely praise its exceptional value and quality, with multiple reports highlighting its stunning appearance and dial details. The watch is noted for its excellent accuracy, with figures around +1.5 to +2 seconds per day. One owner found the HELM Miyako to be tough and versatile, fitting well on a 6.6-inch wrist. Overall, owners consider the HELM Miyako an amazing value and a great watch, worth the wait for its availability.

From video reviewers

Case and dial finishing are praised as competitive with high-end brands. The 200m ISO certification is a strong feature. The included NATO strap is stiff and uncomfortable.
