Introducing the Moritz Grossmann Universalzeit

While a conventional three-hand watch with date will have a numbers wheel underneath the dial painted with a single ring of numbers from 1 to 31 to denote date, the Universalzeit is painted with six rings of numbers ranging from 1 to 24 for the hours. It is attached to a ratchet wheel with 24 teeth, that moves one position on the hour, each time the minute hand passes 12.

Operating the Universalzeit proves remarkably intuitive as well. Time is set continuously via the crown at three o’clock, with the hours in the windows jumping accordingly backward or forward on the hour. Another feature that is especially convenient for the frequent traveler is the ability to adjust the local hour in discrete one-hour steps by operating the pusher at 10 o’clock, independently of the hours in the windowed time zones. In actual use, it will be a breeze for the globetrotter to set local time whether eastward or other westward bound, without affecting the window time display for the designated cities.

Driving all this is the in-house developed manual wind caliber 100.7, beating at 2.5Hz, with a power reserve of 42 hours. All movement components are finished by hand, including the delicate hand-engraved floral pattern on the balance and escape wheel cock, and lettering on the wheel bridge. These details and the traditional finishes on the plates, ratchet wheel which exemplify the best of Glashütte watchmaking, are visible through the display caseback.
