SIGNED ROLEX, DAY-DATE MODEL, REF. 18238, CASE NO. E288240, CIRCA 1990

The lapis lazuli version, the favourite gem of Egyptian pharaohs and Royal dynasties throughout history, is perhaps the most eye-pleasing: not only the deep blue colour is breathtaking, but the stone’s natural inclusions add movement and flair to the dial. These dials are known for their fragile nature and are increasingly scarce to find in unharmed condition.

The Day-Date, Rolex’s first timepiece to display a separate day and date feature, was launched in 1956 and is one of the firm’s most iconic models. Throughout its production, it was available in multiple variances with examples adorned with precious stones, lacquered or hardstone dials.
