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 C63 Valour

The Christopher Ward C63 Valour is praised for its beautiful, deep dial with 3D applied markers and indices, its great look, and its symmetry, with some calling it one of the best-looking and most affordable chronographs available. Reviewers note its Light-catcher case with flowing curves and contrasting brushed and polished finishes, and a matte black dial with applied numerals and sub-dials featuring differently colored hands. The watch is powered by a thermocompensated, chronometer-certified quartz movement, specifically the ETA G10.212 AD, which Christopher Ward claims offers accuracy of +/- 10 seconds per year, though some users question this, citing ETA's stated accuracy of +/- 73 seconds per year. Owners are split on the use of a quartz movement in a watch at this price point, with some preferring mechanical movements, while others defend quartz for its reliability, thinner profile, accuracy, and lower service costs.
