Wow...i love this watch,all stainless steel...with solar cell.I bought it in november 2010 and i never changed the batteries...This came from 1979 and have chronograph,alarm,dual time,alarm and a powerful light.
Assembled probably in honk kong but i think the quality is very good....
Anyone knows how the solar cell works?I never open it...i think there are 2 battery inside but i'm not sure....

Otron made good quality cases I think they were Korean company as the module on one I have say korean made but cant be certain. The actual company name is Olympos Electronics.

Heres a google link that may interest you from Popular science

Heres a Solartime I have here that has the Olympos Electronics on the module case. Although I also have a Limit in exactly the same case. I'll check to see if they have the same module.

I confirm....good quality cases...very massive and good material...well... the watch still works after 33 years (a little miracle)

Two regular batteries. "Solar assisted".

Nice watches.
