Modern watch tastes, in general, have seen an increase in demand for larger timepieces. The Datejust 31mm ref. 178240 is a result of evolving watch trends, offering women a larger case size. The new case wears on a sleek three-link Oyster bracelet secured by a folding Oysterclasp, perfectly balancing out the weight of the case for a comfortable hold on the wrist. As a newer model, this pre-owned Rolex Lady-Datejust also offers several modern upgrades, including the use of Rolex's patented Oystersteel, a scratch-resistant sapphire crystal, a double-sealed waterproof screw-down crown, and a next-generation calibre 2235 perpetual movement.

The watch is beautiful and looked brand new! It was also very affordable.

My impression

Very nice, well designed, quality watch. Was returned because of my wife’s preference for a black dial!
