    My impression

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

    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 ! ***
