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.

Cincinnati Watch Company P-40 A-11 Pilot Black Automatic

Owners widely praise the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its sharp finishing, textured pearlescent dial, and excellent lume. The simple, understated design and comfortable 38mm size are also frequently highlighted. Some owners note the bracelet lacks quick micro-adjustments and the quick-release spring bars can dig into the wrist. One owner found the lume blocks potentially thinner and the font on larger numbers less desirable than a standard typeface, though the seconds hand was considered a success. Overall, owners highly recommend the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its great craftsmanship and value.
