How the Geographic world-time display works
The city selector is the practical distinction of the Geographic’s second-time-zone display. Turn the crown at 10 o’clock to select a location on the 24-city disc. The selected city appears in an aperture at 6 o’clock, and its corresponding time is read on the subdial at 6 o’clock. JLC describes the system as setting the second time zone by location rather than requiring the wearer to calculate the time difference.

Strap fit and buying considerations
Jaeger-LeCoultre lists interchangeable black rubber and blue canvas straps, with a 21 mm lug width and 20 mm buckle width. Those dimensions alone do not establish that a generic straight-end strap will fit the case: check the exact strap reference and curved-end compatibility before ordering an alternative. The official product listing confirms the strap options and dimensions.
For a buyer comparing travel watches, the most relevant confirmed points are the city-based setting method, the 24-city coverage and day/night indication, the 42 mm case, 10 bar water resistance, and the Calibre 939’s stated 70-hour reserve. No comparative performance testing is established here.
