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.

Pinion Pure Bronze

The Pinion Pure Bronze is lauded for its refreshing design, featuring a beautiful layered dial with applied numerals and luminous indexes. Reviewers praise its satisfying manual-winding action from the Unitas 6498 movement, which offers a 45-hour power reserve. One reviewer suggested a satin finish for the crown to match the case back and buckle. Overall, reviewers rate the Pinion Pure Bronze highly for its unique bronze case that patinates over time and its clear, subtly finished dial.
