The Value Proposition The Casio AE1200WH-1A World Timer, At Less Than One Dollar Per Time ...

I don't know exactly when this watch was introduced, but the technology is certainly contemporaneous with the G-Shock - 10 year lithium battery, LCD display, reliable quartz timing package and the ability to display the time in all 31 time zones around the world Its design appears to be derived from, or at least related to, the Casio F-91W, which came out in 1991 and is also still in production; both watches are in the Classic Collection There is also a countdown timer, stopwatch, five daily alarms, and on-demand backlight, as well as an analog LCD display that always shows home time, and, for a wonder, even displays running seconds.
