Tudor Big Block 79170

By Paul Altieri

As a sister brand of Rolex, the Tudor collection bears many similarities to the iconic watchmaker but at a much more obtainable price. An excellent example of that fact is the Tudor OysterDate Big Block ref. 79170 for sale here today. This stunning chronograph mirrors the design of the Daytona in several ways with a similar 40mm case, complete with a Rolex signed crown and a similar three-link bracelet. The "Big Block" 79170 is an evolution of the 9400 series that preceded it. It runs on the celebrated Valjoux cal. 7750 movement and includes a stunning black dial set with contrasting chronograph registers and a date mechanism at the 3-hour marker.

    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!
