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 and reviewers highlight its exceptionally thin 6.6mm case, achieved through a two-hand design, manual-wind movement, and 30m water resistance. The bracelet clasp, however, lacks micro-adjustments. Opinions are divided on the manual-wind nature and absence of a seconds hand, with some finding them unnecessary while others value the resulting slimness and winding experience. One user noted the logo as a drawback. Overall, the Christopher Ward The Twelve 660 is considered good value and well-made by the community, with its thinness being a primary draw.
