Cartier has told its Specialist Retailer partners in the United States that they will benefit from the increased exposure that will come when its watches go on sale on Net-a-Porter and Mr Porter.
Around 60 Cartier models will start selling on the global luxury ecommerce platforms on August 29.
A letter, sent to WatchPro from one disgruntled authorized dealer, says partners will benefit from the increased exposure to 30 million unique luxury shoppers per month.
Net-a-Porter and Mr Porter are both wholly owned by Richemont, the parent organization of Cartier.
Cartier has previously been slow to allow its partners to sell its watches online, at times declining requests from ecommerce retailers to complete transactions on their websites.
Some authorized dealers, such as Govberg in Philadelphia, choose not to sell online.
Tourneau does have the add to bag option online for Cartier watches, Mayors in Florida directs customers to its stores.
