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

Owners widely praise the Longines PRIMALUNA for its attractive style and understated 26.5mm size, with some preferring the automatic for its craftsmanship and heirloom quality. The redesigned 34mm model features an automatic movement, date complication, and polished case design, available in steel or bi-metal with various dial and strap options. Accuracy averages a loss of 1.3 seconds per day across six positions, running 3-4 seconds slower on the wrist, which is within COSC standards. Prices range from EUR 2,850 to EUR 6,600. Overall, owners rate the Longines PRIMALUNA highly for its appealing design and reliable automatic movement.

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.
