Hublot has teamed up with Yohji Yamamoto for a stealthy all-black edition of the Big Bang GMT watch. The collaboration serves to celebrate the grand opening of Hublot's new flagship store in Ginza, Tokyo.

"We are honored to celebrate the opening of our new flagship boutique in Tokyo with fashion designer super star Yohji Yamamoto," said Hublot CEO Ricardo Guadalupe. "This All Black limited edition we created together expresses a simple beauty through the fusion of Yohji Yamamoto’s black design signature and the complicated GMT manufacture movement."

Officially referred to as the Big Bang GMT All Black, the watch makes use of the Hublot Unico manufacture movement HUB1251. The GMT feature allows for two different timezones to be displayed, as the local timezone can be updated instantly with the push of a button.

Completely black, the Big Bang GMT incorporates a black case constructed from micro-blasted black ceramic, black hands, a black dial, and a black rubber strap, while the sapphire crystal is made of smoked sapphire. Yohji Yamamoto's signature is displayed in black at six o'clock, adhering to the monochromatic theme.

"This watch can easily display the time zones of the two cities where I'm based, Tokyo and Paris. Moreover, the hours are invisible," said Yamamoto. "As a person who isn’t always forthcoming, I find that highly amusing. I'm pleased to have taken part in the creation of this model to celebrate the opening of Hublot Boutique in Ginza, a unique, famous and iconic neighborhood of Japan."

The Big Bang GMT All Black Yohji Yamamoto will be available in a limited number of 50, exclusively at Hublot's new Ginza boutique.
