What people say

Owners + reviewers, side by side

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

Massena LAB Uni-Racer

The Massena LAB Uni-Racer is praised for its refined vintage chronograph aesthetic, featuring a 39mm case with unique horizontal finishing, a GPHG-nominated hand-wound Sellita SW510 M movement, and a sector dial with a "big eye" counter. Owners and reviewers highlight its period-perfect Super-LumiNova and snailing on recessed registers, all supported by a 58-hour power reserve and 50m water resistance. On balance, owners and reviewers rate the Massena LAB Uni-Racer highly for its authentic vintage design and refined execution at its price point.

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.
