What people say

Owners + reviewers, side by side

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

Sternglas Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.

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.
