Very sadly in the eighties I bought a kit to build my own calculator watch...God the soldering alone drove me to distraction. Talk about fiddly. But at least it worked. No internet then and tooooo much time on my hands...
Ah my favourite decade the Eighty-ies.
Got this and a calculator one, always dreamed of owning these watches and now I do! It’s pretty decent for the price
Bought one as well. I think the case is plastic but with a metal coating. Battery life is 10 years :D (y)
It's light,but it's a real bit of retro cool. Heat.
