Day-Date 36 White Gold Fluted / Oyster / Black MOP
REF 118239-0116
The Rolex Oyster Perpetual Day-Date is an iconic watch that hardly needs an introduction. Only ever available in precious metals (save for a few prototypes), it was for many years the undisputed king of the Rolex collection and the singular most recognizable 'expensive' watch to the general public. In its present form, the case measures the traditional 36mm. It is driven by caliber 3155. Reference 118239-0116 has a white gold case with fluted bezel. The dial is made of Tahitian mother-of-pearl.

Caliber Notes
Calibre 3155 is a self-winding mechanical movement entirely developed and manufactured by Rolex. It features a day and date calendar disc mechanism. Like all Rolex Perpetual movements, the 3155 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable. Caliber 3155 stands at 6.00mm tall and features 31 jewels. It was introduced in 1988.
