Since its birth in the early 1980s, the best-selling PR 100 has remained true to its name: precise (P), robust(R), and water-resistant to a pressure of 10 bar (100 m). Made from high-quality 316L stainless steel, with excellent corrosion resistance and durability, the collection's aesthetics are preserved over the years. What's more, the tapered crown adds a touch of luxury to this timepiece. This PR 100 model features a 316L stainless steel case and a Swiss Made quartz movement.
