And as a consequence of the domed sapphire crystal, thickness is a whopping 18.55mm. Certainly, the Corum Watches Roulette Bubble 47 Flying Tourbillon isn’t any little watch, and it’s likely to draw a lot of attention. If wrist attendance is exactly what you seek, this watch will send it in spades. Regrettably, regardless of the watch’s little measurements, water resistance is 30 meters, so be wary of liquids.The Bubble watch is so known due to its high domed sapphire crystal, and it is not necessarily just a gimmick. Most watches have horizontal sapphire crystals using anti-reflective coating since they want to prevent distortion. To get Corum’s Bubble view, the contrary is true because the distortion that is caused by its large domed sapphire crystal is what makes the Corum Bubble unique. And since the domed sapphire crystal is indeed intense, the distortion it causes gives the watch an otherworldly look.This is doubly so when you consider that the Corum Bubble 47 Tourbillon watch has large brass skull that makes up the dial. The big hollowed and empty eyes along with the charcoal black dial along with the warmth from domed crystal makes a gothic look that is seldom seen in other watches. Completing the creepy impact is your flying tourbillon at 6 o’clock, which is framed from the mouth of the skull.Speaking of which, the skull at the Corum Bubble 47 Tourbillon reminds me of the skull of Marvel Comics’ Punisher. And to me, it has character, with more menacing and appealing appearances than, say, the skull designs utilized by HYT within their Skull Bad Boy watch or from Bell & Ross in their BR01 Burning Skull “Tattoo” watch (hands-on here).Though legibility might be somewhat influenced by the distortions brought about by the heavily domed crystal, Corum addresses that by giving the Bubble 47 Flying Tourbillon large leaf-shaped palms painted with white Super-LumiNova.
