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.

Christopher Ward The Twelve 660

Christopher Ward The Twelve 660 owners widely appreciate its thin 6.6mm case, achieved partly by reducing bezel and caseback diameters, and its well-made construction and value proposition. However, the community is split on the manual wind and lack of a second hand, with some finding these features unnecessary while others enjoy the interaction and thinness they enable. The bracelet's butterfly clasp lacks micro-adjustments, and some find the 30m water resistance limiting. Overall, owners and reviewers rate Christopher Ward The Twelve 660 highly for its innovative thin case design and perceived value, despite differing opinions on its manual-wind-only, no-date configuration.
