Serica 5303 Diving Chronometer HIGHLIGHTS

Antimagnetic Protection

Featuring advanced antimagnetic construction, the Serica 5303 COSC watches protect their movement with a soft-iron cage that redirects magnetic fields. This enhances resistance beyond the Swiss standard, achieving over 50,000 A/m to ensure exceptional accuracy even in environments with strong magnetic interference.

Versatile Dive Bezel

The luminescent rotating bezel on the 5303 COSC models offers more than just diving functionality. With its clear, legible scale, it tracks immersion time and can also be used to monitor a second time zone, making these watches ideal for both underwater exploration and global travel adventures.
