Despite the extremely difficult manufacturing process, Rolex produced for a short period of time a limited number of natural stone dials. Amongst these, certainly one of the most prestigious produced, is the coral stone dial. This extraordinar ultra-rare yellow gold Day-Date features a soft-coloured coral dial, known as ‘angel skin’ and regarded as possibly the only one known.Manufactured in 1988, the case and bracelet exhibit perfectly intact shapes and originally preserved brushed surfaces, illustrating its exceptional, mint overall condition.The coral dial Day-Date has been named as the “Gulda” by collectors, as a tribute to the famous Austrian pianist Friedrich Gulda, who wore this version during his performances.
