"Octo” is a men's collection by the genius watch designer Gerald Genta. The octagonal case and circular dial combine to create a powerful design. Velocissimo” means ‘high speed’ in Italian. It is equipped with a high-beat column-wheel chronograph movement (caliber BVL 328) that vibrates at 36,000 beats per hour. This high-beat movement can be seen through the see-through back.
