What people say

Owners + reviewers, side by side

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

Serica Ref. 5303 Diving Chronometer

Owners widely praise the Serica Ref. 5303 Diving Chronometer for its excellent wearability, definitive style, and smooth, confident bezel action. The dual scale on the bezel is noted as surprisingly useful, and the crown action, winding, and hacking are reported to work perfectly. One owner describes the Serica 5303-3 as gorgeous and unique, though another notes the crown can appear comically large. On balance, owners rate the Serica Ref. 5303 Diving Chronometer highly for its blend of unique design and robust functionality.

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.
