de GRISOGONO keeps creating trends that have put it at the forefront of the industry in both terms of technical innovations and breathtaking designs. In collaboration with an external lab, the TONDO BY NIGHT timepieces are daytime beauties that also shine at night thanks to Pearly Photoluminescent Composite Fibreglass (PLF), an innovative and exclusive luminescent material and enriched with small pieces of mother-of-pearl that give a stunning finish. This iridescent luminous material on the case and buckle, professionally tested to ensure total comfort, soaks up the daylight in order to lend it a glamorous glow when evening falls.

“I dedicate this watch to happy summer days and glamourous night life. It’s not only a luxury timepiece but can be also worn as a magnificent jewellery piece, with a twist.” explains Fawaz Gruosi, Founder and President of de GRISOGONO. For the TONDO BY NIGHT collection, de GRISOGONO weaves a spell of magic and glamour, once again demonstrating the Brand’s resolutely creative vivacity.
