A historically significant reference, as this is the first Royal Oak with a chronograph complication. This model is housed in the iconic 39mm size, as Gerald Genta intended. This specific reference gained considerable popularity as the legendary chess Grandmaster Garry Kasparov wore one during his professional games. The watch has since been nicknamed "Kasparov" by collectors.
Reference 25860ST.OO.1110ST.01 indicates this watch is fitted with a dark blue dial which shifts from dark grey to blue.
