THE OYSTER PERPETUAL DAY-DATE 40 IN 18 CT EVEROSE GOLD WITH A WHITE DIAL, FLUTED BEZEL AND A PRESIDENT BRACELET.
The Day-Date was the first watch to indicate the day of the week spelt out in full when it was first presented in 1956.
THE FLUTED BEZEL
A ROLEX SIGNATURE
The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch.
It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, in gold on this Day-Date 40.
