1987– Casio AL-180

Rather than say "solar" on the watch, Casio put the term "batteryless", not a usual English word but enough to convey that it did not have a battery. This was probably to convey the attribute of the convenience of not having to change or pay for new batteries, rather than the ecological advantages of the watch.

Comment: This is a nice looking watch, very conventional for the time. The size of the solar panel matches and balances the size of the LCD display. The most notable aspect of the design of this watch is that someone chose to copy it around 2003 and sell it as Casio. See the final photograph on this website for a further discussion.
