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.

Sunrex 321

The compact 37mm case size is a strength. The watch offers versatility with included FKM rubber and leather straps.
