The Dissolved and Noble Gas Lab primarily carries out groundwater age dating by measuring the concentrations of helium-3 (H), a radioactive isotope of hydrogen.Atmospheric atomic bomb testing in the 1950's and 60's bolstered the concentration of tritium in the atmosphere where it can become incorporated into a water molecule and enter the water cycle.

Manufactured by Piquerez, it relied on the increased water pressure to further seal the case as a diver went deeper and deeper, with a caseback pressed more firmly to the case as the diver progressed. The reference switch was accompanied by an increased water resistance to 200m and the replacement of the automatic caliber 19AS with the higher beat movement 290.I’ve tried it on during the meeting (see our Instagram account) and it was actually quite comfortable.The best thing however, is that it isn’t in precious metal (minus the Ring Command Bezel in 18k white gold) like the other Sky-Dweller references.The 42mm case remains sharp, with well defined lugs, but the seller notes that the bottom crown is a replacement part.The caseback features the expected diver embossing and the serial number is engraved on the inside.It is not one of the sports models that you will basically see everywhere, instead it belongs into the category of the Rolex Datejusts and Day-Dates, but with extra functionality.
