Audemars Piguet Selfwinding Chronograph

Audemars Piguet's Royal Oak Offshore Selfwinding Chronograph 26425BC.ZZ.8045BC.01 is a chronograph in 43 mm white gold, set with diamonds. A sapphire crystal covers the silver dial, which shows small seconds alongside the chronograph registers. The self-winding calibre 4409 drives the watch, handling both the flyback chronograph function and the time display. Flyback timing lets the chronograph be reset and restarted in one motion, without stopping it first. Hours and minutes are shown together with the small seconds and chronograph counters on the dial. The white gold bracelet closes with an AP folding clasp. This is a dressed-up take on the Offshore case, built around white gold and diamonds rather than the usual sports-watch finish. Water resistance is not listed on the fact sheet, so no rating is given here.
