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.

Lorier Astra

The Lorier Astra is praised for its outstanding details and design language, hitting a "dressy sports watch" vibe with a beautiful sector dial and lume. Owners note its versatile, do-it-all design with classic proportions and refined details like beveled markers, making it suitable for both formal and casual wear. The watch wears slightly larger than its 36mm case suggests, closer to 38mm, with lugs that taper and curve downward to fit well on smaller wrists. However, the bracelet feels a bit light, some screws are difficult to remove, and the Miyota movement can gain around 8 seconds in 12 hours with potentially offset date numerals. On balance, owners rate the Lorier Astra highly for its dressy sports watch aesthetic and refined details at its price point.
