What people say

Owners + reviewers, side by side

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

Marathon Steel Navigator SSNAV-D Auto

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.

Monta Skyquest

Owners widely praise the Monta Skyquest's build quality and bracelet finishing, with one owner noting its superior articulation and another calling it outstanding for the price. Reviewers highlight its wearability, sporty yet dressy aesthetic, bold aluminum bezel, and bright lume, powered by a Sellita SW330 movement. Some owners find the bezel numeral style polarizing, the GMT hand kinked, and the bezel rotation stiff with silent clicks. The clasp is described as a tight fit and long by some, and the watch wears larger than expected, though its low weight and slim side profile are noted positives. Accuracy for the SW330 movement is considered good by some, with 300m WR and a slim case profile also cited. Overall, owners and reviewers rate the Monta Skyquest highly for its exceptional bracelet finishing and versatile design at its price point.

From video reviewers

The Monta Skyquest GMT features an excellent bracelet, praised by multiple reviewers for its high quality and smooth action. A notable trade-off is the lume brightness, which could be improved. Reviewers disagree on whether the watch's price justifies its cost, with some considering it one of the most expensive GMTs under $3,000 and others viewing it as a strong contender in the under $3000 GMT market.
