Rolex Sea Dweller 50th Anniversary MkII

Date: 17th Jan 2019
Was 11,495.00
Code: 20607S
Manufacturer Code: 126600

Refreshed and revised for its 50th anniversary with a more robust 43mm case, bold red Sea-Dweller text and cerachrom bezel, this newest version aims to be the definitive diver's companion all the way down to 4,000 feet in the ocean. 

In Mint condition, this watch is supplied with the original Rolex inner and outer boxes, stamped Rolex warranty card, green Rolex document holder, instruction booklets and both superlative swing tags, with plastic bezel protector, and case back manufacturer sticker-seal intact.

This timepiece is protected by the Rolex five year superlative warranty until August 2023 and was first launched way back in 1967. When the Hydra VIII mission by Comex (Compagnie Maritime d Expertises) set the world open-sea diving record at a depth of 534 metres in 1988, the watch worn by the divers on their mission was a Rolex Oyster Perpetual Sea-Dweller chronometer. This model was standard equipment for the world leader in marine engineering and has remained exceptionally well regarded within the Rolex community.

This is the most recent Mark II edition, subtly different than the previous version with the inclusion of the Rolex crown just below the 6 o'clock baton.

Having been a customer some years ago, I recommended you to my friend when he decided to sell a Rolex from his collection just before Christmas. As expected, the service he received was exemplary and so I didn’t hesitate to come back to you to when selling my own Rolex this week. Once again, the transaction was smooth, the price was very fair and payment was immediate. The only reason I didn’t buy another Rolex on the spot from John (who is a pleasure to deal with by the way) was because I can’t decide what to go for next. When I’ve made up my mind, I’ll be back to buy - I can recommend you without hesitation.
