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 Diamond

Owners widely praise the Bell & Ross BR-05 Diamond's design and build quality, noting its comfortable wearability and a less derivative appearance in person. The contrast between brushed and polished finishes, along with the blue sunray dial, contributes to its appeal as a versatile integrated steel sports watch. Some owners, however, find the crown to be a bit fussy and criticize the high price relative to the SW300-1 movement. On balance, owners rate the Bell & Ross BR-05 Diamond highly for its striking design and versatile wearability.

Oak & Oscar The Humboldt ExP-02

Oak & Oscar The Humboldt ExP-02 is a 39.5mm stainless steel tool watch featuring a unique, layered aluminum "ghost dial" for legibility and 200m water resistance, powered by a Sellita SW300 movement. Its appeal is limited by a US$2,550 price and an extremely limited production of 20 pieces, with its experimental dial construction done in Chicago. Overall, reviewers highlight the endearing dial and in-house bezel production as key features of the Oak & Oscar Humboldt ExP-02.
