GMT Earth

The ground-breaking spirit that is a hallmark of Greubel Forsey is particularly evident in this timepiece. It incorporates a globe to make three time zone displays visible. By reproducing the Earth’s rotation in real time, this timepiece offers an intuitive view of time all over the world and a day/night indication. With this creation, Robert Greubel and Stephen Forsey totally reinterpreted the very notion of the GMT as a watchmaking complication.
