  • Catalogue Essay

    The present reference 503 demonstrates Patek Philippe’s spirit of continuous innovation. A solar powered clock with full perpetual calendar made in 1964, it merged state-of-the-art technology of the time with the best of mechanical watchmaking . Housing the Patek Philippe caliber 17 250 EQ, ‘17’ refers to the diameter of the movement stated in “lignes”, and the ‘E’ and ‘Q’ are short for Electrique Quantième. A large solar panel on the top of the case supplies energy to a storage device within which in turn transmits energy to power the movement. A battery system is also provided for back up, further illustrating how intelligent and ahead of its time this clock was. The futuristic, asymmetrical dial features large apertures indicating the date and day, whereas a small section on the right side of the dial is indicates the month alongside the timekeeping hands. The present clock’s exclusivity is further enhanced by the prestigious “Tiffany & Co.” signature found on the dial at 6 o’clock. Combined with its superb state of preservation, it’s amongst the finest examples known – and a rare opportunity for the connoisseur.
