Rolex Sea-Dweller 16660 MKl matte dial

Happy that I found another beautiful Sea-Dweller Rolex 16660, Triple Six from 1980 with SN: 6334xxx and a mint MKl matte dial and beautifully blueish age inlay.

As the successor of the famous and well known Sea-Dweller 1665, often called as a transitional reference, this was the first Rolex divers watch to have a sapphire crystal installed and offers a diving depth rating of 4000ft. As a tool watch for deep sea divers, this was obviously a practical and impressive feature. The improved water depth rating was thanks in part to a larger helium escape valve (HEV). Also having the new movement Caliber 3035 installed, which replaced the Caliber 1570 of the previous Sea-Dweller. I do really have a crush on this reference.

This 16660 has a flawless Mark I matte dial, with all lume plots fully intact and color matching hands, both Tritium, no damage or waekness on the dial. Both aged in an even vanilla tone. Bezel inlay has aged in a beautiful blueish tone the only little down-turn is the SL pearl. Case has been polished in the past, but is still in very good fat condition, with slight signs of use. Comes with a 83160 bracelet and 592 endlinks, full 12 segments and divers extension in good condition with resonable stretch, good for another decade to wear. Bracelet itself appears to be original with the watch, clasp is a later sevice replacement with code S U6 (1998). It is not uncommon that these clasps break with the years. They will not be repaired, just replaced, nowadays only in exchange with the original part, that will by kept by Rolex.

Watch comes with it’s original box, and has received an recent Rolex service with service card – so no issues within the next 2 year thanks to the Rolex service guarantee.

Verdict: An amazing 16660 with beautiful mit Mark I dial and cool bezel inlay.
