Marvin 620A Automatic Movement

A Mechanical Heart Developed by Marvin

The Marvin 620A represents the brand’s commitment to developing its own mechanical identity. Rather than serving only as a hidden engine, the movement was created as an extension of Marvin’s design philosophy—combining reliable everyday performance, traditional mechanical character, and distinctive brand details.

Powered by the natural motion of the wrist, the automatic winding system stores energy without the need for a battery. With an approximate 42-hour power reserve, the 620A is designed to deliver stable performance throughout daily wear.

Visible through an exhibition caseback, the movement reveals the continuous rhythm of mechanical timekeeping: the oscillating rotor moves, the gears engage, and the balance regulates each passing second. Selected executions feature Marvin’s crown emblem and decorative finishing, turning the movement into a recognizable part of the watch’s identity.

The 620A platform also supports different functional configurations across Marvin collections, including calendar, day-date, and other display variations. This adaptability allows each watch to develop its own personality while retaining the same mechanical foundation.

More than a caliber, the Marvin 620A is the mechanical signature connecting the brand’s historic watchmaking codes with its contemporary collections.
