Ulysse Nardin’s Marine Mega Yacht

It’s the ultimate watch for owners who like a theme. The Marine Mega Yacht’s (from US$300,000) rose-gold case encloses a striking enamel dial with an interpretation of a ship’s bow. Complications include a flying tourbillon equipped with a cage that looks like a propeller, a 3D moonphase and a mechanism that displays the local tidal height in real time. The 80hour power-reserve indicator features a chain-and-anchor design that gets longer as the movement winds down. You’d almost be forgiven for missing the hour and minute hands.
