The white index dial on the 326938 is the less common configuration within this reference, sitting quietly alongside the champagne as a cleaner, crisper expression of the full yellow gold Sky-Dweller. The solid 18k yellow gold 42mm case carries Rolex's patented Ring Command bezel, which engages the crown across three positions to set the Saros annual calendar and dual time zone independently. Twelve apertures around the dial circumference indicate the month, with a red marker identifying the current one. This example is from 2022, complete full set.
