Patek Philippe: Patek's 1839 Pocket Watch

Company founder Antoine Norbert de Patek owned one of the first pocket watches of his own manufacture, of course. Watch No. 87, dated 1839, ticks dependably to this very day when wound with a key. The video makes history palpable while you watch the regular breathing of the balance, considering how the Patek Philippe manufacture has evolved since this timepiece was crafted there over 175 years ago.
