What people say

Owners + reviewers, side by side

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

Longines PrimaLuna Moonphase

The Longines PrimaLuna Moonphase features a fluid case design and a 72-hour power reserve from its automatic movement. Owners note its accuracy averages 1.3 seconds lost per day across six positions, and 3 to 4 seconds on the wrist, performing within COSC standards. Previously, moon phase models utilized quartz movements, a detail that may not appeal to mechanical watch enthusiasts. Overall, owners rate the Longines PrimaLuna Moonphase highly for its updated automatic movement and reliable timekeeping.

Yema Yachtingraff Seconde/Seconde/

The Yema Yachtingraff Seconde/Seconde/ is a collaboration watch featuring a hand-painted graffiti-style dial with wet paint drips and spray can pushers, powered by a Seiko VK63 meca-quartz movement. One owner noted slight marks on the lugs, bezel, and case of a pre-owned example, rating its condition at 88%. On balance, reviewers highlight the artistic and humorous blend of design elements as the watch's primary appeal.
