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 500M

Owners widely praise the Bremont Supermarine 500M's luxurious appearance and sapphire bezel, with some preferring its design over other luxury dive watches. Reviewers note its updated, legible dial with excellent, long-lasting Super-LumiNova lume. The hardened steel case with anti-reflective coating offers scratch resistance, and the crown placement is a favored feature. Some owners find the 43mm thickness substantial, and one reviewer questions the long-term water resistance of its three-piece case construction compared to traditional designs. Criticisms include the lack of a dive suit extension on the bracelet and a second hand that can be difficult to see in low light, with some finding the bezel markings could be more prominent. Overall, owners and reviewers consider the Bremont Supermarine 500M a handsome, rugged dive watch with a refined look that competes well with more expensive brands.
