The Corum Bubble 47 Flying Tourbillon watch includes a 47mm 18k rose gold case, and further accentuating its size is its large bubble-shaped crown, also made from 18k rose gold. Clearly, the Corum Bubble 47 Flying Tourbillon is no little watch, and it’s likely to draw lots of attention. If wrist presence is exactly what you seek, this watch will deliver it in spades. Unfortunately, regardless of the watch’s little dimensions, water resistance is 30 meters, so be skeptical of liquids.The Bubble watch is so known because of its large domed sapphire crystal, and it isn’t necessarily just a gimmick. Most watches have flat sapphire crystals using anti-reflective coating because they want to prevent distortion. For Corum’s Bubble watch, the contrary is true because the distortion that is caused by its big domed sapphire crystal is what makes the Corum Bubble unique. And because the domed sapphire crystal is indeed extreme, the distortion it causes gives the watch an otherworldly look.This is doubly so once you consider that the Corum Bubble 47 Tourbillon watch has big brass skull which makes the dial up. The big hollowed and vacant eyes along with the charcoal black dial along with the warmth from domed crystal creates a gothic look that’s rarely seen in other watches. And to me, it’s character, with more menacing and appealing looks than, say, the skull designs employed by HYT in their Skull Bad Boy watch or by Bell & Ross within 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 which by giving the Bubble 47 Flying Tourbillon big leaf-shaped hands painted with white Super-LumiNova.
