Last night, I got a rose gold Audemars Piguet Royal Oak 15500 from APS factory and made four changes on it, increase the thickness of the gold coating on the watch, change its dial and hands, replace the auto rotor with a better rose gold auto rotor, do a better polishing on the bracelet. The last photo shows the final comparison, the left one is the watch I have made changes on, the right one is another 15500 in rose gold from APS factory.
