Fun isn't a word that gets bandied around the world of luxury timepieces often, but then Corum is a daring maker like few other. Its Big Bubble watch is exuberant first, but without sacrificing any of the house's precious Swiss luxury. Re introduced for the present day, the domed glass contains a view of the blue planet itself, while a 65 hour power reserve means you'll never run late. The titanium case contrasts satisfyingly against a rubber strap.
