Same watch and same calibre 89-02; the case metal and dial differ. Both are covered by this row's recorded case materials and dial colours. The shot shows the two things the reference exists for: the DST and STD zone apertures reading airport codes, and the home-time subdial with its AUF/AB power reserve. · CC-BY-SA-4.0

Authentication
The colour coding on the time-zone ring is the fastest check. This watch shows 35 zones, not 24, and the odd ones are printed in blue and red for a reason.
Known issues in the market
- Almost no world timer handles zones offset by half or three quarters of an hour. If the ring shows only the usual 24 full-hour cities, it is not a Cosmopolite.
- Glashütte Original is replicated at low volume, so the more realistic risks are service dials and confusion between the many Cosmopolite references across steel, red gold and white gold.
- The Panorama Date here is driven by the same movement as the two time displays. A date that does not track when the home time is advanced across midnight indicates a problem.
| Area | What to check | What is correct | Red flag |
|---|---|---|---|
| dial | Time-zone ring colour coding | 24 full-hour zones in black IATA codes, eight half-hour zones in blue, three three-quarter-hour zones in red. Kathmandu and the Chatham Islands are genuinely selectable | A ring printed in a single colour, or one carrying only 24 cities |
| dial | Two independent time displays | Home time on the subdial at 12 with its own day/night, local time on the central hands with day/night at 9. Both should be settable without stopping the movement | A second time display that only moves with the main hands |
| dial | Panorama Date | Two digits level on a single plane with no dividing bar, the Glashütte Original signature | A visible divider or a step between the digits |
| movement | Calibre 89-02 through the sapphire back | Automatic with an off-centre rotor, 63 jewels, 72 hours, three-quarter plate with stripe finish | A centrally mounted full rotor, which is not how this calibre is built |
| case | Case dimensions | 44mm across and 14mm high, water resistant to 50m | A significantly smaller case; the Cosmopolite needs the diameter for the zone ring |
Common legitimate replacements
- Straps and buckles are consumables. Glashütte Original offers this reference on leather and on a bracelet, so either can be original.
- Servicing a two-zone calendar movement is specialist work; ask where it was last done rather than only when.
Expert resources: Glashütte Original publishes the full technical block per reference on its own site. Monochrome reviewed both the steel and the midnight blue versions with photographs clear enough to read the zone ring.
