Day-Date 40

Oyster, 40 mm, white gold

Reference 228239

This dial features 10 baguette-cut diamonds. Formed in the far reaches of the solar system, metallic meteorite comes from an asteroid that exploded millions of years ago. On the voyage between planets, fragments of this natural extraterrestrial material, primarily composed of iron and nickel, cool by a few degrees Celsius every million years, creating unique, distinctive crystallization within the material that is impossible to recreate on Earth.

Metallic meteorite is rare and challenging to work with, but once it is cut into thin sections and a chemical treatment is applied, the great beauty of its interwoven internal structure is revealed. These fascinating and varied formations are known as Widmanstätten patterns. For its dials, Rolex works with leading experts in the field and selects only the sections of meteorite with a particularly well-formed surface rich in different shapes and reflections.

The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch.

It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, in gold on this Day-Date 40.
