Swiss-made fake Patek Phillipe was the first manufacturer to introduce a series-produced wristwatch incorporating a perpetual calendar and chronograph, the reference 1518 presented in 1941.
A decade later, its successor, the Patek Philippe Perpetual Calendar Split-Second replica watch, was launched offering the same complications but now in a more substantial case highlighted by four fluted, downturned lugs.
These would continue to be produced over the next thirty years. The reference 3970, introduced in 1986, replaced the 2499, with the same complications housed inside a slightly smaller, 36mm case size. Reference 5004 was a true revolution when it was introduced, as for the first time, it offered a split second function in addition to the perpetual calendar and chronograph complications. Produced in yellow gold, pink gold, white gold and platinum, platinum versions remain the most desirable of the four metals.
The present example is overall in mint condition, and is accompanied by the second sapphire crystal caseback, presentation box, and original papers.
Since reference 5004 was discontinued, it has now achieved cult status amongst Patek Philippe watch replica collectors and purists, as it perfectly combines Patek Philippe’s signature design, highest level of complications, and uncompromised approach to quality.
