What people say

Owners + reviewers, side by side

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

Erebus Watches Ascent 40 GMT

Owners widely praise the Erebus Watches ASCENT for its stunning dial and excellent lume, with many finding it gorgeous and beautiful beyond comprehension. The watch is also noted for its comfortable wearability, attributed to its 40mm case, and the bracelet's micro-adjustable clasp and well-finished screws receive specific commendation. Some owners consider the Miyota 9075 movement excellent for the price, with one reporting accuracy of +1 second per day. However, import duties are a significant concern for some buyers, and the polished case sides are noted to lack a scratch-resistant coating. On balance, owners rate the Erebus Watches ASCENT highly for its aesthetic appeal and comfortable wearability 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.
