Senator Cosmopolite

Glashütte Original 2018

ref. 1-89-02-03-02-01
Men's

Few dual-time watches are as thorough as the Senator Cosmopolite in tracking the time around the globe. On most, local time can be set to one of 24 time zones, when in fact certain countries are offset from Greenwich Mean Time (GMT) by 30 minutes or 45 minutes. To be truly complete, a dual-time watch should therefore include 36 zones – which is precisely what the Senator Cosmopolite does. Mechanically complex, it is Simplicity itself to use. Home time is shown at 12 o'clock and set by the crown at 2 o'clock. Tucked into this subdial is a day/night indicator and a power-reserve indicator. Local time, which is centrally displayed, is set by the crown at 4 o'clock to move the hands forward or backward in fifteen-minute jumps. At the same time, IATA airport codes for the cities representing each zone pass in front of the two apertures at 8 o'clock (for standard time and daylight saving time). When the corresponding code appears, such as JFK for John F. Kennedy airport in New York, local time is set.
