PRE-OWNED WATCH CONDITION EXAMINATION

This pre-owned Rolex watch is in mint condition with no signs of wear.  

New Model Rolex Two Tone Sea-Dweller 126603

By Paul Altieri

This year at Basel World 2019, Rolex introduced the first-ever two-tone Sea-Dweller, which was previously only available in steel. Also referred to as "Yellow Rolesor", the two-tone finish pairs 18 karat yellow gold with 904L-grade Oystersteel and is highly sought-after by collectors for its versatility. The ref. 126603 also boasts the brand's coveted Cerachrom bezel with a ceramic insert, a maxi dial with Chromalight luminous plots, and a 43mm case diameter. The sapphire crystal is fixed with a magnifying Cyclops lens, and the Sea-Dweller logo is presented in a striking gold hue that perfectly complements the dual-tone finish of the case and bracelet. The newer-model Sea-Dweller runs on the next-generation calibre 3235 Perpetual movement, which is equipped with a skeletonized Chronergy escapement, high-performance Paraflex shock absorbers, a Paramagnetic blue Parachrom hairspring, and a 70-hour power reserve. This preowned Rolex 126603 will sell quickly, you won't want to pass up an opportunity to add it to your collection.

    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!
