German watchmaker Glashutte Original’s new Grande Cosmopolite Tourbillon comes in a relatively large 48 mm by 16 mm platinum case — at a time when the watch industry is moving towards smaller timepieces — but not without good reason. After all, it is packed with an impressive combination of complications: a world’s first combination of 37 time zones and a perpetual calendar, actually. All destination time and date changes are displayed correctly, thanks to the specially geared perpetual calendar mechanism, which registers changes in both directions, forwards and backwards in time — a function which is currently being patented. And that is not the only patent, there are actually three more. Also, as if that isn’t enough, the Cosmopolite is equipped with a flying minute tourbillon.
