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 16600 timing bezel

By Paul Altieri

The Sea-Dweller was the first dive watch in the Rolex catalog to offer waterproofness of up to 4,000 feet. Its design includes an innovative Helium Escape Valve (HEV), which allows the case to properly decompress while performing deep saturation dives. It also boasts a screw-down case back and a waterproof screw-down crown, protecting the movement within during almost any activity. While the Sea-Dweller was developed for diving, it has since gained an impressive following among preowned Rolex collectors of all professions. Many collectors appreciate the sheer technological prowess involved to create such a resilient timepiece, making it a widely sought-after collector's item. The ref. 16600 that you see here today is suitable for any occasion and includes a standard stainless steel finish and black dial and bezel feature set.

    Better than hoped for

    The condition of the SD 16600 was listed as Excellent. Upon arrival, it was closer to Mint. I could not find anything to complain about the used condition. Even the green sticker was on the caseback. It runs a -1 sec/day and the bezel holds center at 12 o'clock. The lugs' lines are sharp and not polished round. There literally is nothing I can find wrong with this 21 year old watch.

    Very Pleased

    I was stunned at the near perfect condition of my sea dweller 16600 when I received. Bobs was great to work with and the transaction was flawless. Email and phone communication was great and all of my questions were answered. Thanks Jordan and Bobs Watches for peace of mind and professionalism!

    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!
