At a local store, I found a G-Shock but its LCD display was turned off. I haven't found a good size for the car's digital clock style yet (I've copied it onto a blank background once so far, but the size I made watch's display was too small to contain the clock's digits), but it's something to work with.Day/date can be problematic as well. The G-Shock I found was way too busy. Gave up after 15min.
What I'd like to find is the original render for the analog clock dial's hands and markers. It'd make it easier to size up a clock face without having to either guess-test-repeat or copy someone else's work.The first post in this thread lists the dimensions.
