What people say

Owners + reviewers, side by side

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

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.

Vario 1918 Medic Brass

Owners widely praise the Vario 1918 Medic Brass for its crisp enamel dial, easy-to-read numerals, and cathedral hands, noting the brass case develops an attractive patina over time. However, the soft brass scratches easily, and one owner found the lume to be poor. Accuracy varies, with one example running slow by about 10 seconds per day and another owner deeming the Miyota 82s5 movement just okay. On balance, owners rate the Vario 1918 Medic Brass highly for its unique dial and the evolving character of its brass case.
