Introduced in 2021, the Glashütte Original Senator Cosmopolite reference 1-89-02-05-02-70 has a Stainless Steel case of 44.00mm and a Blue dial. Motivation comes from the self-winding caliber 89-02. This movement, with 72-hour power reserve, makes it possible to display the time of day in two time zones at once, freeing the wearer from the need to calculate the time difference. A time zone ring offers a choice of all 35 world time zones currently in use, each of them displayed using an official IATA location code representing an international airport in the relevant time zone.
