Owners + reviewers, side by side

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

Brillier GMT (DUAL TIME) Mechanical Automatic Round 38 mm Gold Case Black Face

The Brillier GMT (DUAL TIME) Mechanical Automatic Round 38 mm Gold Case Black Face earns strong owner appreciation for its dual-time functionality and clean dial design without a date window. The black dial is particularly praised for its depth and presence in person. Owners appreciate the asymmetrical 4 o'clock pusher as part of the design language, though one notes a preference for a thinner case profile. Overall, owners rate the GMT highly for its functional dual-time complication and striking black dial execution at its price point.

Seiko 5 Sports Field series

The Seiko 5 Sports Field series offers an accessible explorer-style watch with a 41mm stainless steel case, 100m water resistance, and a Hardlex crystal. The Field GMT model features a caller GMT complication powered by the 4R34 movement, while the standard Field models use the 4R36 with a 41-hour power reserve. Both models include Arabic numerals coated in LumiBrite and a lumed pearl on the bezel. On balance, the Seiko 5 Sports Field GMT is a well-regarded entry-level explorer watch for its price point, despite its office-style GMT function.

From video reviewers

The prominent five-sided GMT hand enhances legibility and adds a sophisticated aesthetic to the watch. The Seiko 5 Sports Field series offers similar functionality to the Explorer 2 at a lower price, making it a valuable option. Reviewers disagree on whether it's a missed opportunity for Seiko to release this model first, with one reviewer implying it would have been a more logical addition to their lineup.
