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

Owners widely praise the Longines LEGEND DIVER for its faithful retro design, often calling it one of the best vintage reissues, with the 39mm variant lauded for its perfect size and the 42mm for its versatility. The watch is consistently noted as ISO 6425 compliant and powered by the COSC-certified L888.6 movement with a 72-hour power reserve. Reviewers highlight its sophisticated look, clean no-date dial, and the well-made beads-of-rice bracelet, though some owners find the polished center links or overall polished finish dressier than expected for a diver. Owners are split on the 39mm's bracelet, with one finding it too "blingy" and another praising its comfort. The 42mm version's 50mm lug-to-lug measurement is considered long by some, while others find it comfortable. One owner of the 42mm model reported a scratched hour hand after 15 years, and another noted the original leather strap's poor quality.

From video reviewers

The Longines LEGEND DIVER features a unique blend of vintage design and modern functionality, with 300 meters of water resistance and a 72-hour power reserve. The watch's historical significance and aesthetic appeal are notable strengths. The 7-link bracelet is also a notable feature, although its quality and comfort are not explicitly discussed.
