Between 1979 and 1991, Audemars Piguet transformed 19 examples of Model 5402 by gemsetting the bezel rim. The addition of 64 diamonds (eight per side) changed the reference of the watches to 4187.
Derived from Model 4100, the Royal Oak 4153 (renamed 14153 in 1984/1985) was set with 80 brilliant-cut diamonds on the bezel.
Born from the demand of the German market for a watch imbued with the "Offshore spirit", as well as the desire to rejuvenate the Royal Oak collection, Model 25721 created a scandal when it was launched at the Basel Fair in April 1993.
Created in only one example, this Haute Joaillerie model is entirely paved with baguette-cut diamonds and enhanced with a mother-of-pearl dial.
The Royal Oak Offshore 25855SC is a gemset interpretation of Model 25770. The abbreviation "SC" indicates that its case combines a steel case middle (S for Steel) with a white gold bezel (C derives from BC meaning white gold), which is set with 32 baguette-cut sapphires (approx. 3.19 carats).
