Genuine Rolex Cal 3235 Part #315 Barrel Complete

The Genuine Rolex Calibre 3235 Part #315 Barrel Complete is an authentic mechanical movement component designed for the Rolex Calibre 3235 automatic winding movement — the precision engine inside many modern Rolex models.

This complete barrel assembly includes the barrel drum, central arbor, and pre-assembled mainspring, forming the heart of the movement’s power storage and delivery system. The barrel functions as the primary power reservoir for the movement: it stores energy when the automatic rotor winds the mainspring and releases that energy in a controlled manner to drive the gear train and regulate the watch’s timekeeping.

Rolex’s Calibre 3235 is a modern, high-performance automatic movement noted for its improved efficiency, reliability, and extended power reserve (approximately 70 hours) compared with earlier calibres.

This part is genuine Rolex, suitable for professional watchmakers servicing or restoring Rolex watches powered by calibre 3235 that require a replacement barrel assembly to maintain torque consistency and long-term accuracy.
