If there’s one thing Hublot knows how to do, it’s how to throw a summer party. This year, the brand has dialed up both the heat and the style with the launch of the Big Bang Unico Summer 2025, in vibrant ceramic colors that tell a story of sun-drenched days and electric nights.

The heart of the action pulsed in Mykonos, where Hublot Ambassador and sprinting legend Usain Bolt joined Friend of the Brand Mattia Vitale of the DJ trio Meduza for a beachside celebration. Beats were dropping over the Aegean, waves lapped the shore, and a sea of guests, from collectors to Hublot insiders, were draped in colors. That scene, incidentally, encapsulates what the new Big Bang Unico Summer 2025 delivers. Presenting a vibrant orange case, crafted from Hublot’s ultra-light and ultra-durable micro-blasted ceramic, is complemented by a sky-blue bezel, reflecting the shimmering sea beyond the cabanas. 

“Summer and its festive spirit have been celebrated at Hublot for the past 8 years. The Big Bang Unico Summer 2025 reflects what Hublot stands for: bold, vibrant and unforgettable moments. A celebration of summer, joy, friendship, team spirit and above all the incredible people who make Hublot what it is” explains Julien Tornare, CEO of Hublot.

Now the Big Bang Unico Summer 2025 isn’t all good vibes and glam, it’s got muscle too. The watch runs on the in-house caliber Unico HUB1280 to support the main hours, date and chronograph functions with a provision of up to 72 hours of power reserve. Speaking of which, Hublot’s in-house Unico movement has greater architecture than you think.
