Hublot Spirit of Big Bang Sapphire 45mm

Machining a tonneau case from solid blocks of sapphire crystal is one of the most difficult exercises in modern case-making — sapphire is nearly as hard as diamond — and Hublot leads the industry in it. The result is a watch that appears to float on the wrist, its movement suspended in glass.

The skeleton HUB4700 chronograph inside completes the total-transparency concept. Produced in small numbers; a genuine rarity in the secondary market.
