Three case versions are created: steel (ref. 16520), 18k gold (ref. 16528), and steel and gold (ref. 16523). They are fitted with metal bracelets in the corresponding style, although a later gold case version (ref. 16518) is offered with a leather strap.
This model immediately becomes a “cult item”, is sort after by Rolex enthusiasts worldwide with lengthy waiting lists. It remains in production until 2000.
This wonderful gold version belongs to the first series, as can be noted by the ‘R’ serial number, and is fitted with the rare four-liner porcelain dial and applied diamond hour markers. The illustrated dial proudly exhibits the ancient and sophisticated “email grand feu” enamel art, which is still today one of the most complicated techniques used in watchmaking. It involves high temperature enamelling, the French name stands for “big fire”, a process during which the metal oxides are heated from 800 to 850 degrees. This process creates a perfectly fat and smooth surface displaying a homogeneous colour tone. The work of the master enameller is truly demanding and requires a high sensibility. He must master the firing without causing crevices or unevenness and not exceed a thickness of two tenths of a millimetre. This ultra-rare 16520 reference, showing the R99 serial number between the lugs and termed by collectors “the Porcelain dial”, delivers absolutely amazing results. Notice the spectacular brightness of the white tone and the powerful impact given by the indexes and scripts which seem to glide softly on the dial.
This watch not only come in wonderful condition, but also has its original sales kit including box and papers.
