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 C65 Aquitaine GMT

The Christopher Ward C65 Aquitaine GMT is widely praised for its vintage aesthetic, featuring a "Beach Sand" dial, box sapphire crystal, and a contrasting blue ceramic bezel. Owners and reviewers alike highlight its beautiful design, noting it appears even better in person than in press photos, with a highly polished sapphire bezel insert and warm ivory font that precisely matches the dial's lume pods. The 41mm case size is considered a positive downsize, and its 200m water resistance, combined with a lightweight and rugged build, makes it a versatile traveler. The date at 6 o'clock is noted for providing balance and elegance. On balance, owners and reviewers rate the Christopher Ward C65 Aquitaine GMT highly for its stunning vintage design and versatile, robust build.
