Times of the world at a 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.

The exquisitely crafted 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 design.

Setting the time windows and the main time 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.

When the minute hand moves over the 12, the ratchet wheel and with it the disc move forward by one position. The disc is precisely positioned by a ratchet spring. Thanks to the optimal alignment of the numerals on the disc, the hours are aligned horizontally in the windows, making it easy for the wearer to read them.

Setting the main time separately via the crown 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 mechanism allows the operator to engage the crown in two positions at 10 o’clock and then use a pusher function to correct the hour hand independently of the disc. In the middle position, a stop prevents the pusher from being operated. This prevents accidental adjustment of the time.

The Grossmann manual winder with pusher

The in-house developed manual winding mechanism with pusher contains a perfected hand setting mechanism, which eliminates two potential problem areas: avoiding the ingress of foreign particles during the adjustment process and altering the hands unintentionally when pushing the crown back into place.

After a short pull on the winding crown, the mechanism switches to hand setting and simultaneously stops the movement. The crown immediately returns to its original position, allowing the hands to be adjusted precisely. The movement is then restarted using the pusher below the winding crown without having to move the crown again. At the same time, the mechanism is reset to winding mode.
