If I recall, Rolex used the fluted bezels for a purpose;
Rolex states as follows;
"THE FLUTED BEZEL
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 caseback, 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, always in gold."
I guess Rolex will stick to fluted bezels in a skydweller, more so that the fluted bezel is also the "command ring" that has to be gripped easily to actuate the functions.
