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.

Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322

Owners widely praise the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 for its gorgeous, color-popping black mother-of-pearl dial and good case finishing, with some appreciating its distinct bead-blasted case and H-link bracelet. The $375 price is noted as a strong value for a true mother-of-pearl watch. However, opinions are divided on the dial text font and the Islander logo, with some finding them unattractive and others seeing them as minor issues on an otherwise appealing tool watch. On balance, owners rate the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 highly for its striking mother-of-pearl dial and value proposition.
