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 CONQUEST

Owners widely praise the Longines CONQUEST for its high-quality finishing, excellent value, and versatile design, with many citing the L888.5 movement and 72-hour power reserve as key strengths. The watch is frequently noted for its comfortable bracelet and attractive dials, offering comparable quality to more expensive alternatives. However, several owners and reviewers point out the lack of micro-adjustment on the bracelet clasp as a significant drawback, with some also noting the polished surfaces are prone to micro-scratches and the lume is inconsistent across variants, with only some models featuring lumed hands. On balance, owners and reviewers rate the Longines CONQUEST highly for its impressive finishing and value proposition, particularly its robust movement and versatile wearability.
