The silvered dial is alive with convenient functions and an appealing design. Note the stretched Arabic numerals at 2, 4, 8, and 10 that give the impression of the curve of the Earth.

The Earth, indeed, and your place upon it is fully represented here with this watch’s perpetual calendar that accounts for leap years and allows you to read the day at 9, the month at 12, and the date at 3. The world time indicator at 6 can be adjusted via the pusher at 4.
