The Richard Mille RM UP-01 ‘Ferrari,’ launched in July 2022, currently holds the title of the ‘Thinnest Watch in the World’ with its 1.75mm thickness. This remarkable timepiece surpasses the Bulgari Octo Finissimo Ultra at 1.8mm and the Piaget Altiplano Ultimate Concept at 2mm in slimness. 

Unveiled in Maranello, Italy, this watch is not only ultra-thin but also impressively lightweight. Its movement weighs a mere 2.82g, and the total weight of the watch, including the strap, is less than 30g. The distinctiveness of the RM UP-01 lies in its casing design. Unlike its rivals, Piaget and Bulgari, which integrate the case as the baseplate, Richard Mille has ingeniously constructed the entire movement within a closed case.The RM UP-01 is an exclusive, limited edition with only 150 pieces available, each priced at $1,750,000.

This watch has garnered attention from various celebrities and notable figures. Pharrell Williams, Jackie Chan, and Sheikh Rashid bin Humaid Al Nuaimi, the son of the ruler of the emirate of Ajman, have all been spotted wearing it.

Competition over the title world’s thinnest watch has been going on for some time. Richard Mille's collaboration with Ferrari in July 2022 broke the internet and impressed the watchmaking industry with their new release, the Richard Mille UP-01 Ferrari. The 1.75mm thin watch is named to be the world’s thinnest watch on the entire planet, setting a remarkable world record.

In July 2022, when the watch was released, it quickly garnered attention, and the first celebrity spotted wearing it was none other than the young and talented F1 driver, Charles LeClerc. This came as no surprise, considering that Charles LeClerc is the brand ambassador for the timepiece. His endorsement further solidified the watch's status in the world of motorsport and horology.

Following in the footsteps of LeClerc, another Scuderia F1 driver, Carlos Sainz Jr., was among the first celebrities spotted wearing the watch. This comes as no surprise, given that the watch was created in collaboration with Scuderia Ferrari, making it a natural choice for the team's drivers to proudly wear.
