This is again a consequence of design because the actual time-telling dial is quite small and the hands must be limited to this radius. The applied markers are also a nice touch.Īnother common complaint with world timers that a lot of collectors have are the hands, which tend to be small. Any text printed on the dial (especially the city ring and 24-hour ring markers) is high contrast and quite legible despite the small font. Here, the map seems to be etched onto the dial like a bas-relief and gives the dial some texture. Many have dials with maps printed on them that tend to look flat and a bit dead but not in the case of the Geophysic Universal Time. However, there are small elements that can make or break a world timer dial. I can’t think of a way to have a world map on the dial and still maintain a minimalist appearance. The movement is visible through the caseback and has the usual decoration in the form of Geneva stripes, heat blued screws, beveling, and a decorated gold rotor.īy their nature, world timers have busy dials. The caliber 772 beats at 4Hz and offers 40 hours of power reserve. The Gyrolab balance is designed to be more aerodynamic and to improve rate keeping accuracy over time. The caliber 772 is also equipped with the brand’s proprietary Gyrolab balance. I’m not entirely sure how Jaeger-LeCoultre managed to add a world timer complication but reduce the total number of parts by one, but they have. In addition to Jaeger-LeCoultre’s Geophysic watches, the ones that I can think of immediately are the Habring2 Erwin and the Grönefeld One Hertz.Īn interesting factoid (and one that Ariel is fond of repeating) is that the caliber 772 movement in the Geophysic Universal Time has exactly one component less than the movement in the time-only Geophysic True Second, the caliber 770. Given the mechanical complexity in designing a true seconds movement and the attendant premium in price, it’s not entirely a surprise that the complication is uncommon. Also known as a true seconds complication, this was historically (much before the advent of quartz) prized by watch owners as it helped them tell time precisely to the second. The simplest way to describe it is to imagine the seconds hand behaving the same way as it might on a quartz watch – a distinct tick for each second. A deadbeat seconds is a little more uncommon, as far as mechanical complications go.
