19. Hublot Black Caviar Big Bang – $1 Million
Featuring 501 baguette-cut black diamonds complemented by 18-karat white gold, the Hublot Caviar Black Big Bang has a mesmerizing design, yet it still remains simplistic. A smooth, black rubber strap leads toward the polished, black ceramic case and bezel. Inside the case, a sapphire crystal with anti-reflective treatment rests next to a Hublot logo. This watch uses self-winding movement, which means there’s no need to replace batteries. The timepiece charges up by the movement of your arm while you’re walking, and once it’s fully charged, the Big Bang can work for up to 42 hours before running out of power.
