What people say

Owners + reviewers, side by side

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

Bell & Ross BRS BLACK DIAMOND EAGLE DIAMONDS

The Bell & Ross BRS BLACK DIAMOND EAGLE DIAMONDS is a 39mm ceramic quartz watch with a subsidiary seconds dial and SuperLumiNova. Owners describe it as stunning, with aesthetics outweighing movement quality for some, and find it incredible on the wrist. Opinions on its appearance are split, with some finding it elegant and others ugly. On balance, owners and reviewers find the Bell & Ross BRS BLACK DIAMOND EAGLE DIAMONDS to be a visually striking watch, with its aesthetic appeal being its primary draw.

Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic

Owners widely praise the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic as a tough, underrated tool watch with lifestyle appeal, highlighting its robust build and tritium lume for excellent legibility. However, its 46mm size is a common criticism, with some finding it heavy and top-heavy, and the OEM rubber strap stiff. One owner noted the watch runs about 10 seconds fast after three days, and the ETA 2836-2 movement offers approximately two days of power reserve. On balance, owners and reviewers rate the Marathon JDD (Jumbo Day/Date) Anthracite Diver's Automatic highly for its robust tool-watch build and legibility, despite its substantial size.
