Atomic clock radio signal syncing watches are so last year. Citizen just decimated the coolness factor of those watches with the Satellite Eco-Drive watch. This timepiece isn’t just a concept, but will actually be produced as a limited edition later this year – and may have its tech show up in later watches. In a nutshell, the watch keeps its time super accurate from syncing with the navigational satellites that orbit Earth as opposed to syncing with radio signals that are broadcasted from local atomic clocks.
