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.

Hamilton Jazzmaster Open Heart Auto

The Hamilton Jazzmaster Open Heart Auto is noted for its dressy yet versatile design, featuring striking gradient dials and intricately shaped cutouts that reveal the H-10 movement. It boasts an 80-hour power reserve and Nivachron hairspring. The watch is available in 36mm, 40mm, or 42mm stainless steel cases. On balance, the Hamilton Jazzmaster Open Heart Auto is appreciated for its visually engaging dial and movement display at its price point.

From video reviewers

The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.
