Longines has produced two Conquest V.H.P. models to mark ten years of its partnership with tennis legends Steffi Graf and Andre Agassi.
There will be only 10 numbered pieces of the watch for men and 10 for ladies.
All 20 will be auctioned with proceeds going to Children for Tomorrow and The Andre Agassi Foundation for Education, two charities founded by the couple.
The men’s version of the Conquest V.H.P. Stefanie Graf & Andre Agassi Foundations has a black dial, while the ladies’ model has a white mother-of-pearl dial and a case set with 70 diamonds.
In tribute to the Roland Garros tournament in Paris, where Longines is an Official Partner, both versions feature touches of orange on their hands, indexes and the rubber strap, as a nod to the iconic Parisian clay courts.
Both models bear an engraved logos on the case backs: Andre Agassi Foundation for Education on the men’s version and Children for Tomorrow on the ladies’.
Longines bought the number 1 watch of each model for $100,000, and will display them at its museum.
