PRE-OWNED WATCH CONDITION EXAMINATION

This pre-owned Rolex watch is on overall excellent pre-owned condition with only minor surface wear to the bracelet.

used Mid-Size ladies Rolex Datejust 178240

By Paul Altieri

The Rolex 178240 is a contemporary take on the ladies Datejust that features a larger, mid-size 31mm case with polished lugs and an engraved inner reflector ring, a flat-link Oyster bracelet closed by an Oysterclasp, and a classy white dial topped with a fully-lumed display and an automatically changing date window. The case is hermetically sealed via a process that involves screwing the Twinlock screw-down crown and a screw-down case back into the Monobloc middle case, allowing it to withstand depths of up to 330 feet. This resistance protects the calibre 2235 movement within, allowing the mid-size Datejust to accompany you almost anywhere you roam.

    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 ! ***

    The purchasing process was quick and easy once I finally made my selection. Bob’s customer service was excellent. All my questions and concerns were addressed to my satisfaction. But most important of all, my husband loves his new watch!
