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 Twelve X Black Shadow

Owners widely praise the Christopher Ward Twelve X Black Shadow's impressive finishing for its price point and the quality of its bracelet. Some owners, however, feel the $4,865 price is high for the brand, while others argue it offers strong specifications for the money. Reviewers note the skeletonized COSC-certified SH21 movement provides a 120-hour power reserve, but legibility suffers due to the skeletonization and the watch's increased thickness is noticeable. One owner reported sharp edges on bracelet links and unfinished clasp surfaces, leading to a return, despite finding the case and dial appealing. On balance, owners and reviewers rate the Christopher Ward Twelve X Black Shadow highly for its finishing and value, with the skeletonized movement being a key draw.
