Prince Michael of Kent became Backes & Strauss's Royal Brand Ambassador in 2018, after the CEO asked him at a London event; he visited the Geneva workshops in November 2018 and co-designed the 2019 Royal Kent Collection. The maker now lists the partnership on a page titled past collaborations, without an end date.
