If you’re on first-name terms with your cabin crew, you need a worldtimer. As complications go, it’s a simple one: the world’s time zones are emblazoned on a rotating bezel; spin your home city to 12 o’clock and you immediately know the time anywhere else on Earth. Which helps prevent partner-waking phone calls when you add eight hours from Shanghai time, rather than subtract.
Frederique Constant’s Worldtimer model also features a globe-engraved dial, to double down on that jet-setting aesthetic, in an otherwise restrained, steel case you can wear from meetings to after-dinner drinks.
