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.

Bremont Terra Nova 40.5

The Bremont Terra Nova 40.5 Date Bronze is highlighted for its CuAl7Si2 bronze alloy case, which provides a warm, luxurious appearance and develops a gradual patina. It includes a gradient green dial with prominent Super-LumiNova numerals and a 40.5mm diameter. The watch is powered by the caliber BE-36AE, offering a 38-hour power reserve and 100m water resistance. The Bremont Terra Nova 38, a time-only field watch, features a 904L stainless steel case and vintage-inspired beige Super-LumiNova. Reviewers noted a preference for a screw-down crown and caseback for a field watch. On balance, reviewers praise the Bremont Terra Nova 40.5 Date Bronze for its distinctive bronze case and attractive dial, while noting the Terra Nova 38's utilitarian design and a preference for more robust water-resistance features on a field watch.
