Finally! Some 12 years after joining forces with Patek Philippe and the Swatch Group for initial studies at the Swiss Centre for Electronics and Microtechnology in Neuchâtel, Rolex has introduced silicon into one of its movements! Ladies are the first to experience Rolex’s newest feature: the diamond set 34mm Oyster Perpetual Datejust Pearlmaster has inherited the 2236 calibre fitted with the new silicon Syloxi spring. With 4 patents exclusive to Rolex and a fifth for the material itself shared with Patek Philippe and Swatch Group, this spring has a very unique shape: the coils aren’t all the same thickness and the fittings on both sides have been completely redesigned. The COSC certified calibre will be fitted in men’s watches soon. The Pearlmaster comes in 18 carat yellow gold, white gold and Everose and costs between 37,000 and 100,500 CHF.
