Breitling will increase UK prices by 6% in the UK on March 1.
Sources speaking to WatchPro, who asked not to be named, said that retailers are being informed about the increase this week.
Breitling retailers in the UK have enjoyed a considerable advantage over their peers in Europe and the US since the pound dropped in value after the Brexit vote last year.
Almost all luxury brands have now increased UK prices, in some cases more than once.
Some have used the UK to clear global inventories to relieve overstocked retailers in parts of the world where sales have slowed ahead of the trade buying season.
