What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Astor + Banks Sea Ranger M2

The Astor + Banks Sea Ranger M2 is widely praised for its balanced design, excellent legibility, and strong GADA (go-anywhere, do-anything) capabilities, featuring 300m water resistance and a scratch-resistant coating. Reviewers note its comfortable 40mm case size and good lume, though one source describes it as good but not great. The movement is a Sellita SW200 adjusted by the brand, with accuracy reported around ±8 seconds per day. The pre-order price is $650, with a standard price of $850. On balance, reviewers find the Astor + Banks Sea Ranger M2 to be a compelling option due to its functional design and robust specifications.

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.
