The watch was originally released in 1976 for a price of $158 (based on digital-watch. Come information) and has a few more features than the watches a few years prior. This model has time memory (which seems to be some sort of dual time), calendar, and stopwatch, as well as a small bulb-based light.
The LCD display shows 3 1/2 digits (so no 24-hr display as the first digit can only be a 1), but pm denoted by a symbol in the upper right of the display. The seconds display works with the numbers 0-5 in boxes above the time, so 0 means 0-9 seconds with the number showing for 5 seconds and flashing for 5 seconds before going to the next 10-sec symbol.
The watch is powered by the less common AG5 battery accessible through a separate battery hatch. Time setting was not intuitive, and after many trial and error attempts, I found a scan of the manual on digital-watch. com. What I was missing was that the adjust button needs to be pressed when the 50-59 second number is displayed in order to work (for some reason unknown to me).
