Calibre 2455 is distinguished by the ceramic ball bearings incorporated into the 22-carat gold oscillating weight adorned with a motif inspired by the Maltese cross. They eliminate the need to lubricate the bearing while ensuring a prolonged lifespan. A stop seconds mechanism serving to bring the watch to a halt and enable accurate adjustment, along with a frequency of 28,800 vibrations per hour, constitute major assets for this mechanical self-winding calibre bearing the Hallmark of Geneva.
