Peren One

The Peren One chronograph is praised for its successful blend of minimalist and '80s retro styles, featuring a clean bi-compax dial design and thoughtful case execution. It utilizes the reliable Seiko VK64 mecha-quartz movement, offering mechanical chronograph functions. The 40.6mm steel case provides 200m water resistance and a balanced, tool-first aesthetic with mixed finishing, complemented by the absence of a date and running seconds for a tidy dial. On balance, reviewers rate the Peren One highly for its retro-modern aesthetic and the value offered by its mecha-quartz movement.
