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.

Seestern S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.
