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.

Longines LEGEND DIVER BRONZE

The Longines LEGEND DIVER BRONZE is widely praised for its striking green fumé dial and heritage design, with reviewers noting its value and the thoughtful inclusion of a hypoallergenic titanium caseback. Owners find the watch comfortable and stylish, appreciating its retro styling and internal rotating bezel. However, some owners report that the bronze case patinas slowly, developing a muted darkening, and that the lume is not strong. A few owners also find the long lugs make it too large for smaller wrists, and one notes the clasp is a scratch magnet and the bracelet lacks end links. On balance, owners and reviewers rate the Longines LEGEND DIVER BRONZE highly for its captivating dial and vintage aesthetic at its price point.
