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 (Ti) Titanium

Owners and reviewers widely praise the Christopher Ward Twelve X (Ti) Titanium for its exceptional value, lightweight titanium construction, and comfortable wearability, with case thickness noted as under 9mm by some and around 12.3mm by others. The watch features a COSC-certified movement, either a Sellita SW300-1 or a skeletonized SH21 with a 5-day or 120-hour power reserve, and reviewers highlight excellent lume performance and improved legibility on skeletonized dials. Some find the bracelet's one-step micro-adjustment clasp convenient, while others report sharp bracelet links and unfinished clasp interiors, and one owner noted the "Arctic White" dial appeared silver. There is a split on Christopher Ward design originality and the potential for case and bracelet chamfers to be prone to dings.
