What people say

Owners + reviewers, side by side

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

Maen Grand Tonneau Ultra Thin

Owners widely report the Maen Grand Tonneau Ultra Thin features a La Joux-Perret D101 manual-wind movement and a double-layer enamel dial. Some owners criticize the bracelet design and find the dial too small and lacking indices. One owner describes the Maen Grand Tonneau Ultra Thin as "hideous with a good movement." On balance, owners are divided on the Maen Grand Tonneau Ultra Thin, with some appreciating its movement and dial while others find its design unappealing.

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.
