HUBLOT – Big Bang Unico Red Sapphire 45mm
Time+TideHUBLOT – Big Bang Unico Red Sapphire 45mm
Sapphire is commonly used on watch crystals because its extreme hardness (second only to diamond on the Mohs scale) makes it highly scratch-resistant. At the same time, this toughness makes sapphire a difficult material to work with for more complex components, which is why using it to craft an entire case is something only attempted by brands at the very highest levels of horological sophistication. The Unico Red Sapphire is Hublot’s first red variation of the sapphire case.
