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 stylish, understated design and comfortable 26.5mm and 34mm case sizes, with some preferring the quartz for its lower maintenance and others the automatic for its craftsmanship. The automatic movement, an L899.5 or Caliber L899, offers a 72-hour power reserve and exhibits consistent accuracy averaging a loss of 1.3 seconds per day in testing, though it runs 3-4 seconds slower on the wrist. The redesigned collection features a curvier case with contemporary lug integration and is available in steel or bi-metal. On balance, owners and reviewers appreciate the Longines PrimaLuna for its elegant styling and reliable automatic movement, though some find its brand prestige and design less compelling compared to certain luxury alternatives.

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.
