Avante-garde design is nothing new to Hublot fans, but the Swiss brand’s latest Big Bang Unico GMT delivers on the practical front, too. Beneath the openwork dial, you’ll find an in-house caliber HUB1251, with fully integrated dual time zone complication, but it’s the easy-to-read day/night disc used to indicate whether it is AM or PM in the second time zone that will appeal most to stylish travellers. hublot.com
