Now available, an exceptionally rare and possibly unique Patek Philippe Annual Calendar “AC Milan” reference 5035R-028 in rose gold.
Commissioned in 1999 by AC Milan and produced in a limited run of just 100 pieces for players, owners, and senior members of the club, this little-known reference is one of the most unusual modern Patek Philippe limited editions. Based on the landmark reference 5035 - the world’s first annual calendar wristwatch - the 5035R-028 differs considerably from standard production examples through its distinctive dial layout, dagger-style hour markers, and commemorative caseback and rotor engraving.
Cased in rose gold and fitted with a beautiful silver soleil dial, the watch carries a very different character to the regular 5035 family. What makes this particular example especially fascinating, however, is the dial itself. Compared with other known examples, this watch displays a number of notable differences, including an accented “Genève” signature, the absence of “SWISS” at six o’clock, non-luminous dagger markers, and a unique month display configuration. Together, these details strongly suggest that this may be a prototype dial, or potentially a very early development ex*****on for the limited run.
Whatever the explanation, the watch has since returned to Patek Philippe for servicing and remained entirely unchanged, further supporting its originality. Numbered 92 of 100 on its Certificate of Origin, the watch is accompanied by its original commemorative AC Milan box with inset plaque, alongside the original outer card for the leather wallet, also carrying its matching “92” sticker. The case remains in exceptional overall condition with all hallmarks present to the rear of the lugs, and the watch was serviced by Patek Philippe in Geneva in August 2025, remaining under manufacturer warranty until August 2027. A remarkable piece of Patek Philippe and AC Milan history. The watch is available for viewing in London and purchase worldwide. Please get in touch for further information and pricing.
