Azzurro-blue dial

The floral-motif dials combine three different finishes – sunray, matt and grained. High-technology finishing techniques were required to create this motif, a shining example of refined dial-making expertise. The textural effects are further enhanced by 24 diamonds of varying sizes, which illuminate the centre of each flower.

Fluted bezel

Fluted bezel

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 Datejust 31.
