PRE-OWNED WATCH CONDITION EXAMINATION

This pre-owned Rolex watch is in very good pre-owned condition with a few observable scratches on the bezel/bracelet.

pre owned Rolex Mid-Size DateJust 178240 Roman Markers

By Paul Altieri

The Rolex Lady-Datejust features a luxurious design that is effortless and widely sought-after. The first Datejust was introduced to market in 1945, bringing with it the world's very first automatically changing date display. A few years later, in 1957, the ladies 26mm variation debuted, and recently, the mid-size 31mm option was also introduced to market. The 31mm, or mid-size, Datejust is the perfect option for women who seek a feminine yet slightly more contemporary statement piece. The ref. 178240 that you see here today is an Oystersteel example of the line that also features a newer calibre 2235 Perpetual movement with a 48-hour power reserve, a three-link bracelet secured by an Oysterclasp, an engraved inner reflector ring, and a gorgeous black dial topped with silver hour markers and hands.

    I have made several purchases and one sales through Bob’s. The order process, payment, processing, and most importantly delivery have all been absolutely flawless. Very quick and efficient. I never look anywhere else for used Rolex.

    Superb site and transaction, phenominal delivery time. Some slight confusion concerning the special discount at the time. I didn't receive it. No big deal I would not hesitate to purchase another rolex from Bob's ! ***
