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 BR-05 Blue Diamond Eagle

Owners widely praise the Bell & Ross BR-05 36 MM Blue Diamond Eagle's design, dial, and the contrast between brushed and polished finishes, finding it a compelling integrated steel sports watch. One owner notes the crown can be fussy. The £4k price is considered high, especially given the SW300-1 movement. On balance, owners find the Bell & Ross BR-05 36 MM Blue Diamond Eagle's design and finishing compelling, though the price point is a significant consideration.

Marathon Steel Navigator SSNAV-D Auto

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance.

The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.
