Audemars Piguet Selfwinding "50th Anniversary"

Audemars Piguet presents the Royal Oak Selfwinding "50th Anniversary", reference 15551ST.ZZ.1356ST.01, in a 37 mm steel case. The case measures 9.1 mm thick, a size built for the women's line while keeping the Royal Oak's established proportions. A steel bracelet closes with a folding clasp, and a sapphire crystal covers the blue "Grande Tapisserie" dial. Diamonds are set on the watch, adding brightness against the dial's textured pattern. The self-winding movement is AP's calibre 5900, paired with an oscillating weight finished in the same steel tone as the case. Beyond hours and minutes, the watch shows central seconds and the date. Water resistance is rated to 50 metres, enough for daily wear without special caution.
