Audemars Piguet Selfwinding "50th Anniversary"

Audemars Piguet's Royal Oak Selfwinding "50th Anniversary", reference 77450ST.OO.1361ST.01, comes in a steel case measuring 34 mm across and 8.8 mm thick. The silver dial sits under a sapphire crystal. Inside is the self-winding calibre 5800, which drives the centre seconds and date functions. The date display sits at the edge of the dial without disturbing the symmetry of the layout. A steel bracelet with an AP folding clasp closes the watch on the wrist. This anniversary reference carries the grey tones associated with the current Royal Oak design evolution, along with a rhodium-toned oscillating weight marking the model's fiftieth year. Water resistance is rated to 50 metres.
