The Patek Philippe ref. 5040 was produced for approximately 15 years, between 1992 and 2007. It was joined by a sister reference, https://www.relogiosdeluxo.cz/category/replica-rolex/ the https://www.replicarolexorologi.co/categoria-prodotto/explorer/ ref. 5041, with a slightly different case and dial design, between 1995 and 2003. In 2012, the tonneau-shaped ref. 5940 was added to the Patek Philippe https://www.replicarolexorologi.co/categoria-prodotto/air-king/ catalog as a spiritual successor to the ref. 5040 and 5041. Unfortunately, there is no current-generation tonneau-shaped Patek Philippe QP, so the ref. 5040 still represents your best chance to buy.
