Functionally, this is a full-fledged multifunction analog/digital quartz watch with all the bells and whistles you'd expect from G-Shock: a 31 time zone world timer, five daily alarms, a 1/100th of a second stopwatch, countdown timer, and date. There's a "Super Illuminator" LED light under the dial to supplement the lume on the hands. The gold accents reflect the nighttime-in-Tokyo vibe Geller wanted to be part of the design – "my favorite time in Tokyo is walking through the city in the middle of the night, when it is impossible to sleep because of the jet lag," he says – with a thin arc of gold above the running seconds display in an arc between 9:00 and 12:00 on the dial. There's also a function indicator in the form of a gold disk between 3:00 and 5:00, which rotates to point at the chosen function (you'll find yourself pushing the function button for no reason, just to watch it do its thing). I'd have preferred a Tough Solar module but I think that would probably not have been, from a practical standpoint, consistent with the design goals.
