What people say

Owners + reviewers, side by side

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
