Stepping up in Glashütte Original's range
The Senator Cosmopolite exists because the standard GMT complication, useful as it is, was never truly built for the modern international schedule. Rather than tracking a second time zone, the calibre 89-02 accounts for the full complexity of global travel — the 35 to 37 IATA zones including the awkward half-hour and quarter-hour offsets that catch travellers between standard meridians — with separate day/night indication for both home and destination. It is a watch drawn from a very specific brief, and the movement required to answer it is built to Glashütte Original's highest manufacture standards: three-quarter plate with Glashütte ribbing, a swan-neck regulator for fine adjustment, and a skeletonised micro-rotor carrying a 21-carat gold weight, all delivering 72 hours of reserve. At 44mm the case wears with appropriate authority for what it contains — this is not a watch that pretends the complication is simple — but 14mm of thickness is genuinely controlled given the movement architecture beneath. The white matte dial keeps the Arabic numerals and dual zone windows readable rather than decorative, the blued hands providing clear separation from the chapter ring in different light conditions. The Louisiana alligator strap, delivered from the factory, carries the formality the brief demands.

Learn more about Glashütte Original
Glashütte Original is the direct corporate descendant of the East German state watchmaking industry. When the Soviet administration expropriated Glashütte's private manufacturers after the Second World War — A. Lange & Söhne among them — it consolidated them into a single enterprise, VEB Glashütter Uhrenbetriebe, which produced watches for the Eastern Bloc for four decades.
After reunification the enterprise was privatised, and in 1994 it took the name Glashütte Original. It therefore inherits both the archives and the tooling of the pre-war houses and the industrial capacity built under the GDR.
That inheritance shows in vertical integration unusual even at the high end. The company makes its own movements, and its own dials, through the Pforzheim dial manufactory it acquired in 2006 — a capability most houses buy in.
The house signatures are German: three-quarter plates, duplex swan-neck fine adjustment, hand-engraved balance cocks, and skeletonised rotors in double-G form. The Panorama Date, a large date display where both discs sit on one plane so no dividing line interrupts the numerals, is its most distinctive complication and a deliberate improvement on the standard big-date module.
The Senator, Sixties, and Seventies collections cover classical and retro-industrial ground respectively. Swatch Group acquired the company in 2000.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How long does it run for when it's not worn?
About 72 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What size strap does it take?
21mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's.
Cheapest place to buy
Goldsmiths is the only UK retailer we track stocking this reference, so there is nothing to compare it against today.
