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.

Christopher Ward C63 Sealander Extreme GMT

The Christopher Ward C63 Sealander Extreme GMT is widely praised as a competent and comfortable tool watch offering excellent value. Reviewers consistently highlight its impressive Globolight lume, providing excellent legibility, and its well-proportioned 41mm brushed steel case. The Sellita SW330-2 movement is noted as reliable, though its standard accuracy is stated as ±20 seconds per day, and its GMT functionality is considered less advanced than some alternatives. One owner notes the green dial can be an acquired taste, and hands and markers are considered less refined than those on significantly more expensive watches. The Christopher Ward C63 Sealander Extreme GMT is priced attractively at €1,895 on bracelet. Overall, owners and reviewers highly regard the Christopher Ward C63 Sealander Extreme GMT for its rugged, travel-ready design and impressive lume at its price point.
