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.

Bremont Altitude Perpetual Calendar GMT

The Bremont Altitude Perpetual Calendar GMT is a highly exclusive piece, with one owner noting its $44,000 price point raises questions about its target audience and suggesting it may be a limited production showpiece. Reviewers highlight its refined Trip-Tick case, now featuring softer curves, a 42mm diameter, and a 12.23mm thickness in grade 2 titanium, though the oversized crowns are flagged as a potential drawback. Overall, owners and reviewers acknowledge the Bremont Altitude Perpetual Calendar GMT as a distinctive, albeit niche, high-complication offering with a notable case refinement.
