Rolex Sea-Dweller, 126603

We are proud to present the impressive Rolex Sea-Dweller Steel & Gold for sale in unworn condition, fully checked and authenticated in our accredited workshop.

Originally developed in 1967 to compliment the already popular Rolex tool-watches, the Sea-Dweller was developed originally for saturation divers working for SeaLab who were spending a lot longer underwater than your casual diver. Because of those extreme conditions and depths, the divers noticed that the crystal would pop out of the case during decompression due to the helium particles in the case. So, Rolex developed the Helium release valve under their patent and thus the Sea-Dweller was born and over 50 years later has become an iconic and integral part of the Rolex family.

This version the reference 126603 first produced in 2019 is set in a robust 43mm stainless steel case with a yellow gold uni-rotational bezel with a black Cerachrom insert. The dial is black and features large Chromalight hour markers for superior legibility underwater, as well as the matching gold Sea-Dweller text and date feature at 3 o’clock. Encased in sapphire crystal glass and with a Triplelock screw-down crown as well as the signature helium release valve giving the watch a water resistance up to 4000ft. The watch is fitted with a matching stainless steel and gold Oyster link bracelet with a folding Oysterlock clasp with Glidelock extension system.

Originally purchased in late 2022 and in unworn condition, the watch is still protected by its manufacturers guarantee until 2027. Coming supplied with the original inner and outer Rolex boxes, instruction manual, guarantee booklet, swing tag, green seal, leather card holder and new style international warranty card.
