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 C1 Moonphase 37

Owners widely praise the Christopher Ward C1 Moonphase 37 for its aventurine dial and moon display, with one user awarding it a perfect score for its celestial theme. However, the lack of hour markers and lume-less hands make time-telling difficult, and hands can disappear against the dial. The COSC-certified movement averages +2.3 seconds per day, and the bracelet clasp is noted for comfort. The moonphase complication itself is reported by one owner to be inaccurate despite manufacturer attempts to correct it, though other users view such complications as primarily decorative. The 38-hour power reserve is considered short. Overall, owners rate the Christopher Ward C1 Moonphase 37 highly for its striking aventurine dial and moon focus, despite challenges with legibility and the practical accuracy of its moonphase complication.
