In 1997, one hundred examples of the ref. 5057R were made to commemorate Singaporean retailer Cortina’s 25th anniversary. It is among the first limited edition retailer editions that had a complication.
The dial and hobnail pattern are now considered classic 1990s. The screw down sapphire exhibition back contains the words “Cortina Jubilee Watch”. Besides being one of the most novel and surprising Patek Philippe limited editions of its time, the Attestation features the signature of Philippe Stern, an elegant personalization from a different time.
