Rolex is known for employing rare and fragile materials in their watch dials. This Day-Date reference 18238 in 18k yellow gold also features a marble dial and, due to the fragility of the stone, the manufacturing of the dial requires extreme precision to expose the day and date apertures. A highlight of the ‘Important Watches’ live auction on 9 November as part of #SothebysLuxuryWeek, with an exhibition preceding the auction 4-8 November at the Mandarin Oriental in Geneva.
