Rolex Oyster Perpetual Day-Date 40 in Platinum with Ice-Blue Dial (reference 228236-0012)

Rolex has launched a new Oyster Perpetual Day-Date 40 model in a platinum case with an instantly recognizable ice-blue dial and president bracelet.

Fluted bezel, a cornerstone of Rolex’s aesthetic heritage, is found only on some Classic models in the Oyster Perpetual collection. Until now it has only been made in 18 ct gold. This new Oyster Perpetual Day-Date 40mm watch (reference 228236-0012) features platinum fluted bezel.

Introduced in 1956, the Rolex Day-Date was the first calendar wristwatch to indicate, in addition to the date, the day of the week spelt out in full in an arc-shaped window at 12 o’clock on the dial. The day of the week is available in a choice of 26 languages. Watches in the Day-Date range are made only of precious metals – 18 ct yellow, white or Everose gold or 950 platinum.
