What people say

Owners + reviewers, side by side

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

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.

Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation

The Seiko Prospex Marinemaster Marinemaster 1965 Diver’s Modern Re-interpretation is noted for its refined, slimmed-down 39.5mm stainless steel case with a "super hard" coating and a box-shaped sapphire crystal. It offers 200 meters of water resistance and is powered by the slim Caliber 6L37 automatic movement, which has a 46-hour power reserve and an accuracy rating of -10/+15 seconds per day. Reviewers highlight its wearability and functionality as a dive watch, with one noting it as Seiko's thinnest diver ever at 12.3mm. However, concerns are raised about Seiko's continued reliance on the 62MAS design, with one reviewer wishing the Marinemaster remained a separate line, and the bracelet's end-links appearing mismatched in initial images. Its price of A$4,650 is considered high given its specifications compared to competitors.
