The Rolex Day-Date ref. 18238 with a black dial and diamond hour markers is a classic expression of Rolex’s flagship luxury model from the late 1980s and 1990s. Crafted entirely in 18k yellow gold with a 36mm case, fluted bezel, and President bracelet, it carries the full prestige of the “President” watch. The black dial creates a strong contrast against the gold case, while the diamond indices add a refined, jewelry-like touch without overwhelming the design. Powered by the reliable automatic caliber 3155 with double quickset functionality, the 18238 combines high-end luxury with everyday mechanical robustness. It remains one of the most elegant and authoritative vintage Day-Date configurations, valued for its bold presence and timeless prestige.
