The Bubble watch is so called due to its high domed sapphire crystal, and it isn’t necessarily just a gimmick. Most watches have horizontal sapphire crystals with anti-reflective coating because they want to prevent distortion. For Corum’s Bubble watch, the reverse is true because the distortion that is due to its large domed sapphire crystal is what makes the Corum Watch Hk Replica Bubble unique. And because the domed sapphire crystal is so extreme, the distortion it causes gives the watch an otherworldly look.This is doubly so once you consider the Corum Bubble 47 Tourbillon watch has large brass skull which makes up the dial. The large hollowed and empty eyes along with the charcoal black dial along with also the warmth from domed crystal creates a gothic look that’s seldom seen in different watches. Completing the creepy effect is your flying tourbillon at 6 o’clock, which can be 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 personality, with much more menacing and appealing appearances than, say, the skull designs employed by HYT within their Skull Bad Boy watch or from Bell & Ross within their BR01 Burning Skull “Tattoo” watch (hands-on here).
