Pre-Owned Watch Condition Examination

This Rolex watch is in overall excellent condition.

Tudor Black Bay GMT 79830RB

By Paul Altieri

The Tudor Black Bay ref. 79830RB debuted at Basel World 2018 and, like the Rolex GMT Master II, boasts an independent 24-hour hand on the dial. This feature can be adjusted without disturbing the other hands on the dial, allowing the wearer to read up to three time zones at once. The ref. 79830RB also boasts a feature set that is somewhat vintage-inspired in the form of beveled edges along the lugs of the case, a rivet-link bracelet, and an older-style Tudor logo on the dial and rose on the crown. Another notable feature of this particular secondhand Tudor is the bezel, which showcases a deeper blue and red hue on the insert, which can be mistaken at first glance as a Coke bezel as opposed to a Pepsi. Modern yet inspired by the classics, this Black Bay GMT is an intriguing addition to any watch box.

    3rd Bob's watch

    So far Bob's is 3 for 3 with me ordering on Thursday and them processing/shipping on Friday for a Saturday morning delivery. Every watch has been in perfect condition. This Tudor GMT is a great watch for any collector or traveller. Many of the brilliant craftsmanship characteristics you notice about your Rolex will be present on the Black Bay. For one example not mentioned in any reviews I've seen, all edges are rounded and polished ever so slightly as to not look super rounded off, yet when slipping on and off the watch it feels smooth as glass.

    Tudor BB GMT

    Really easy experience buying online. Great selection but you have to be constantly checking for the perfect watch. The process didn't take long. I placed the order on Friday night, Monday the order was processed, and Tuesday morning the watch was already in my house. Having Affirm as an option of payment is great, especially with the 0% deal! Really nice watch, and it was just as described. I would recommend buying from you guys to my friends!

    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!
