I have finally found a LottoWatch (please see the photos below), produced by relatively known brand - OTRON, a brand of Olympos Electronic Co, Hong Kong - that have produced many interesting LCD watches in the late 70's-early 80's, including some early Solar powered LCDs!
https://books.google.ro/books?id=o9QDAA ... ny&f=falseAnd because I could not find online the settings/number generator instructions, here they are:
I. Watch Setting:1. Press short the upper right button in the main time mode
2. Change between sec:min:hour with the upper left button
3. Increment sec:min:hour with the lower right button
Similar in dual time, alarm mode...
BUT
4. To set the day:month - the above steps in the dual time (T2) screen :)
Press short upper right button to finish the settings
II. Generating random numbers:The watch may generate/choose 5 to 26 random numbers, out of 30 to 49 values (e.g. from choosing 5 numbers out of 30, 6 out of 49 etc etc ....up to 26 numbers out of 49!)
1. Press lower left button for 3-5 secs, One should see now a "nn-NN LO" screen - e.g. "06-49 LO" meaning choose 6 random numbers out of 49 available :))
2.Press short the upper right button, the NN number started to blink
3. Change between nn (e.g.06) or NN (e.g. 49) with the upper left button
4. Increment nn-NN with the lower right button. Press short upper right button to finish the settings
FINALLY PRESS UPPER LEFT BUTTON TO GENERATE THE NUMBERS! Good luck on the lottery!
