Geneva, June 2nd, 2022: A monumental collaboration in watchmaking is born. ZENITH makes its most awarded movement from the golden age of chronometry competitions available to acquire for the first time ever. An idea initiated by Phillips’ Aurel Bacs and Alexandre Ghotbi, with whom ZENITH had already worked with on unique pieces and exclusive editions, Phillips in Association with Bacs & Russo invited renowned independent watchmaker Kari Voutilainen to restore and hand-decorate a batch of ZENITH Calibre 135-O movements, all of which took part and won in observatory chronometer competitions. The result is a contemporary chronometer produced in a series of 10 pieces and sold exclusively by Phillips in association with Bacs & Russo.
