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 40

Owners widely praise the Christopher Ward C1 Moonphase 40 for its captivating aventurine dial and photorealistic, luminescent moon, with many receiving compliments and finding it a stylish, lightweight, and comfortable daily wear. The in-house Calibre JJ04 module's 128-year moon tracking is a notable feature. However, multiple owners find the lack of dial indices and bezel markings, along with unlumed hands, makes precise time-telling difficult, with some describing it as more of a jewelry piece than a functional timepiece. One owner experienced a movement issue requiring warranty repair within the first year, and another noted frustration with customer service. The 40.5mm case size is considered sporty by some, and the design is described as "shouty" by a few. On balance, owners highly rate the Christopher Ward C1 Moonphase 40 for its stunning moonphase display and aesthetic appeal at its price point, despite legibility concerns.

From video reviewers

The aventurine dial and Globolight lume are praised for their realistic starry night effect. The 3 ATM water resistance is a significant limitation.
