What people say

Owners + reviewers, side by side

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

Boldr Odyssey Original

Owners widely praise the Boldr Odyssey Original's value, with one noting the blue dial and bronze case develop an amazing patina and another highlighting the personalized purchase experience. The watch is available for $350 and comes in its original dive case. One owner observed that the 12 o'clock markers on a bronze variant were not straight. Overall, owners rate the Boldr Odyssey Original highly for its developing patina and strong value proposition.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
