The Glashütte Original Senator Cosmopolite reference 1-89-02-02-02-30 is a limited edition of 10 pieces created for the brand's Shanghai SKP boutique. It features a stainless steel case and a silver-white dial with blue accents. 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.
