This number stands for each year of the life of Jacques Piccard. Phlipp and Jerrel have an official approval by the son of Jacques Piccard, Bertrand. The Rolex DeepSea Sea-Dweller that has been used, underwent quite a metamorphose. A DLC coating, engraving on the caseback and a single red wording of 'DeepSea' (referring to the red printed vintage Sea-Dwellers).
The watch comes in a special box and with an additional NATO strap. This project has been a crown on the work of the creator of this special edition, who is – besides watch dealer – also a true passionate of Rolex wrist watches and its history.
