Audemars Piguet Perpetual Calendar

Audemars Piguet's Code Perpetual Calendar, reference 26441OR.OO.D405CR.01, measures 38 mm in rose gold. The case is fitted with a sapphire crystal over a grey dial. Inside is the self-winding calibre 7138, a perpetual calendar movement adjusted entirely through the crown. The watch shows date, month and weekday alongside a moon phase display, all tracked without correction until the next century. It runs on a green alligator leather strap closed by a folding clasp in rose gold. Water resistance is a modest 30 metres, enough for everyday wear but not for swimming.
