What people say

Owners + reviewers, side by side

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

Lorier Hydra SIII

Owners and reviewers praise the Lorier Hydra SIII for its value, GMT functionality via the Miyota 9075 movement, and classic travel-diver aesthetics. Some reviewers note the finishing is simple or a tad rough around the edges, while others find it good for the price. Accuracy figures range from +7 to +8.5 seconds per day. The domed Hesalite crystal may exhibit distortion. Overall, owners and reviewers rate the Lorier Hydra SIII highly for its feature set and value proposition in a travel-diver format.

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.
