PRE-OWNED WATCH CONDITION EXAMINATION

This pre-owned Rolex watch is in overall excellent pre-owned condition with no significant or observable signs of wear.

pre owned Rolex Sea-Dweller Model 16660

By Paul Altieri

The Rolex Sea-Dweller ref. 16660 - aka the "Triple Six" - is considered the first modern reference in the line as it was the first Sea-Dweller to feature a scratch-resistant sapphire crystal, a unidirectional timing bezel, and an increased waterproofness of up to 1,220 meters/4,000 feet. The ref. 16660 also features a larger Helium Escape Valve, a white date mechanism - compared to its predecessors that utilized a date wheel with a silvery finish - and a higher-beat calibre 3035 perpetual movement. The example that you see here today is a rare variation of the Triple Six Rolex that displays the time on a very desirable matte black via painted Tritium luminous hour markers and central Mercedes hands. The painted hour markers are indicative of a vintage tool watch, while features such as a high-beat calibre 3035 Perpetual movement and a sapphire crystal, give the ref. 16660 a more modern aesthetic.

    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!
