Real men have their own Atomic Clocks
You'll need to act quick if you want one--they're only releasing three, and they're a little pricey at $2.7M each:
"Swiss watchmaker Urwerk recently introduced its limited edition atomic clock.The Urwerk AMC has been in development for nearly a decade, and takes inspiration from Breguet’s ‘sympathetique’ watch/clock combination invention of the turn of the 19th century. The Urwerk AMC uses a solid 55-pound block of aluminum for a foundation, and winds and adjusts the watch when it is in place within."
