Day-Date 40 40mm President Bracelet and 18 KT Yellow Gold with White Dial and Fluted Bezel

The fluted bezel of a Rolex watch is a symbol of prestige. Originally, its grooved design was used to securely fasten the bezel onto the case, aiding in making the watch waterproof.

The fluting on the case back was identical to the Rolex signature feature seen today on the Day-Date 40 in gold. This fluting serves both a practical purpose, as it is screwed onto the case for waterproofness, and an aesthetic one. It has become a hallmark of distinction over time and with the help of special Rolex tools.
