presenting the Urwerks 'King Cobra' UR-CC1

On the UR-CC1, there are two horizontal indications displayed by two cylinders: one for the (jumping) hours and a retrograde cylinder for the minutes. The seconds are displayed by a rotating disk on the dial.
The UR-CC1 is the result of more than three years of research, development, production and testing to ensure that the rotation and instant fly-back of the large hour and minute cylinders was achieved without compromising accurate timekeeping.

herenext up, we have the ultra-"how'd they do that" Louis Vuitton Tambour Mysterieuse Calibre LV115

The focus of the design lies in its transparent face with a mechanism that appears to float in the center. However, the secret to this magical feature is actually quite simple—the hour and minute hands are supported by two transparent sapphire disks. The watch is also capable of running for up to eight days on a single winding.
