Hublot has collaborated with Yohji Yamamoto for a covert all-black version of the Big Bang GMT watch. The coordinated effort serves to commend the grand opening of Hublot’s new leader store in Ginza, Tokyo supposedly in May 2020.

“We are honored to celebrate the opening of our new flagship Boutique in Tokyo with fashion designer super star Yohji Yamamoto. 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.” said Ricardo Guadalupe the CEO of HUBLOT

Officially alluded to as the Big Bang GMT All Black, the watch utilizes the Hublot Unico make movement HUB1251. The GMT feature allows two distinctive timezones to be shown, as the nearby timezone can be refreshed right away with the press of a button.
The all-black design of this new limited edition expresses a philosophy symbolising the very essence of the brand. Literally, the model is completely black; it has a black case made of micro-blasted black ceramic, black hands, a black dial, and a black rubber strap. Even the sapphire crystal is made of smoked sapphire.

“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.”
Limited to 50 pieces, the Big Bang GMT All Black Yohji Yamamoto will exclusively be available at the Hublot Boutique Ginza.
