Next question would be, how could it look like? A dweller has a helium valve, one doesn’t need in th e sky. The Sea-Dweller is the ultimate Submariner, for extreme use, underneath the surface. A Sky-Dweller would logically be the opposite, the ultimate GMT-Master. That means it’s going to be bigger then the maxi 40 mm GMT ceramique case, logically more like the DeepSea Sea-Dweller in 43mm ( for AP & Hublot clients ) So a big pilot kinda of Rolex with something new added, like a special turning bezel, quick set of GMT time with pushers, combined with a chrono? Lots of newly Rolex patented designs could have been used, like this one ” Timepiece provided with a device for controlling functions and/or time indications ” (

Interesting notes :
“
There are several documents which suggest that a turning bezel fitted with annular teeth engaging a radial axis pinion should be used to adjust a time function, either the hour spindle, the date, the day, the month or even the year. One ofthese arrangements is described in EP 1584000. It should be noted that in this arrangement the bezel can only be used to adjust one of the functions mentioned.”

Finally, U.S. Pat. No. 360,415 discloses a winding and time setting mechanism in which the stem has only one degree of freedom in rotation, passage from the winding position to the time setting position being carried out by means of a camacting on a yoke. Such a system only allows a choice between the control of two functions and/or time indications. Now the object of this invention is to make it possible to increase the number of functions and/or time indications which can decontrolled."
