Can you imagine? This malachite dial took millions of years to form. Luckily, Rolex 'only' had to make it fit this rather spectacular Datejust.

Dating to 1979, this ref. 16018 combines an 18k yellow gold Oyster case with a dial cut from natural malachite. The stone's pattern gives the dial plenty of depth, with shades ranging from bright emerald to deep forest green. There are some hairline cracks in the stone, but the pattern remains beautiful, and the contrast with the 18k yellow gold is just as good as ever. Each piece has its own pattern, and since it is formed by nature, it is impossible to find two identical stone dials. We have a soft spot for the clean look of stone dials. No hour markers to distract from the pattern, just the applied Rolex coronet, the date aperture at 3 o’clock and the gold text printed directly onto the stone. Sometimes, less really is more.

The ref. 16018 is the 18k yellow gold version of the classic 36mm Datejust, complete with its iconic fluted bezel and recognizable case design. The hallmarks on the caseback remain clearly visible. While the Datejust is most often associated with the Jubilee bracelet, this example is fitted with an 18k yellow gold President bracelet with concealed clasp. Both the case and bracelet remain in very good condition, retaining their sharp lines and showing a warm patina that has developed on the gold over the years.

Millions of years went into forming the stone, and Rolex put it to good use in 1979. Nearly five decades later, this wonderful Datejust still has plenty going for it.
