Pre-owned Rolex Oyster Perpetual ref. 177200 (2010) is a very collection-worthy ladies’ Rolex. At 31mm in diameter, it is slightly larger than traditional women’s Rolexes yet smaller than the men’s range, so it will suit a broad range of wrist sizes. It’s entirely cased in Oystersteel here, which many will find quite durable, timeless, and versatile. What really caught our eye, though, is the sharp black dial, which is decorated with Explorer-style hour markers featuring silvered Arabic numerals and luminous batons. The watch is rated waterproof to 100 meters, so you don’t have to worry about getting it wet while washing your hands or taking a quick dip in the pool. It also features a self-winding movement, so the time is always correct as long as you wear the watch often enough to keep it wound. Shop Rolex Oyster Perpetual 31 Collection
