This Rolex Day-Date reference 18238 is one of the strongest stone-dial expressions of the five-digit series. Its self-winding caliber 3155 brought the double quickset generation to the Day-Date, a practical step beyond the earlier 18038 and part of what makes this reference such a natural hold within the line. Here that mechanical update meets a black onyx dial, paired with Arabic day and date wheels that sharply distinguish the watch from standard examples. In 18k yellow gold, the case measures 36mm across and 12.4mm thick, the proportions that fixed the Day-Date's identity for decades while keeping it composed on the wrist. Rolex also moved the series to a sapphire crystal, giving the reference a more modern edge without disturbing its compact architecture. For a collector who wants the classic Day-Date format with a more exacting dial treatment, this is where the reference becomes notably harder to replace.
