A timekeeper for globetrotters, the Moritz Grossmann UNIVERSALZEIT makes it possible to see the current time in six different time zones simultaneously across the world at a single glance. Designed in the shape of a world map, the dial uses time windows precisely aligned with coordinates and city names as a means of providing orientation in terms of time and geography. A total of six windows displays the hour from 1 to 24 in each of the six cities.

Ref. MG-003072
To inquire about availability please phone 303.572.1111

The exquisitely crafted solid silver dial of the UNIVERSALZEIT indicates the time to the minute all around the globe. Featuring oceans, continents, longitude and latitude, the ensemble of time windows and the hour, minute and second hands all come together to create a well-ordered layout in a classically elegant 44.5 mm stainless steel case.
