Seiko 5 Sports Field series

Ref. srpj81
Sport
Available in

The Seiko 5 Sports Field series is praised for its value, offering an accessible explorer-style watch with a GMT complication and excellent legibility thanks to LumiBrite on the dial and bezel. The watches feature a 41mm stainless steel case, 100m water resistance, and are powered by either the 4R36 or 4R34 movement, both with a 41-hour power reserve. One reviewer notes the inclusion of a compass bezel with a lumed pearl and fully lumed Arabic numerals on the dial for the non-GMT models. Overall, reviewers consider the Seiko 5 Sports Field GMT models good value under 500 euros.
