UNIVERSALZEIT, the latest model from the independent manufacturer Moritz Grossmann, makes it possible to see the current time in different time zones around 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. Daylight-saving time is not observed in the cities selected. This means that the UNIVERSALZEIT indicates the actual time all year round and no adjustment is necessary.
MORITZ GROSSMANN UNIVERSALZEIT CENTRAL SECOND STAINLESS STEEL
The new calibre 100.7 of the UNIVERSALZEIT was specially developed by Grossmann’s designers in the manufactory.
Setting the time windows and the main time via the crown at 3 o’clock-
The hours in the time windows and the main time are set via the crown at 3 o’clock. When the minute hand passes 12, the time in the time windows jumps forward by one hour.
A disc connected to a 24-tooth ratchet wheel moves beneath the dial. This is printed with a multitude of numerals from 1 to 24, each arranged at an angle of 15 degrees across a total of six rings.
Setting the main time separately via the crown at 10 o’clock-
The main time hour hand is then corrected via the pusher mechanism at 10 o’clock.
The hour hand of the main time can be moved backwards and forwards separately in hourly increments using the quick adjustment mechanism. This does not change the time display in the windows.
The UNIVERSALZEIT’s elaborate manufacture movement is given an appropriate setting by a stainless steel 44 mm case with a brown, hand-stitched alligator leather strap.
