It currently holds the record for the world’s thinnest mechanical watch, measuring 1.75mm in total thickness. Collectors value this reference for its technical construction, which utilizes a Grade 5 titanium monobloc baseplate to ensure rigidity despite its profile. The manual-winding caliber RMUP-01 features a patented ultra-flat escapement and eliminates the traditional winding stem in favor of two integrated crowns on the dial face. The movement provides a 45-hour power reserve and 5,000g of shock resistance. On the secondary market, this reference typically commands prices in the $1.7 million to $2.2 million range, significantly above its initial retail price of approximately $1.88 million.
