In 1969, Mr. Andersen as a hobby created his first “Bottle Clock” and then earned the moniker “Watchmaker of the Impossible” by the international press at the Montres et Bijoux show. Just like the ship in a bottle you have to wonder “how does he do that?”. It took watchmaker Svend Andersen 5! (five) month to construct this clock inside a bottle through bottle’s mouth measures 18mm.

Only 35 clocks was made (each is unique design), this is 33rd bottle. Unique piece from world-known watchmaker.

This is a highly collectible timepiece as Svend Andersen is a well regarded independent watchmaker from the prestigious AHCI & watches. Svend ANDERSEN launched his own workshop in the late 70’s after having spent 9 years at Patek Philippe. He started his career as independent watchmaker by first manufacturing cases for Italian collectors. Satisfied with the high quality of the work, the watch collectors started to ask for their own bespoke timepieces (called “pièce unique”). Since then ANDERSEN Genève has been developing complicated watches like the annual calendar, perpetual calendar, and jumping hour calendar.

Runs great and all functions work as expected. Please take a look at the photos for condition. A fine investment that is guaranteed to increase in value as the years go by.
