Rolex Sky-Dweller 326934

The blue dial is the one collectors chased hardest on the steel Sky-Dweller, a deep sunburst that shifts from bright cobalt to near-navy as the light crosses it, white gold markers and a red month marker set against the field. Behind it runs Rolex's most complicated watch, a Saros annual calendar and second time zone worked through the fluted white gold Ring Command bezel, the month read across twelve apertures at the rim. The 42mm steel case holds the automatic caliber 9001, a chronometer with a 72-hour reserve. Dated June 2021, a full set with box and papers. See the rest of our Rolex watches at Marc Samuels.
