I built an interactive simulator of the Elektronika 1, the first Soviet LED watch (1976): press the buttons, read and set it like the real one
I sell Soviet watches in Paris and about twenty Elektronika 1 have gone through my hands. Buyers always ask the same thing: how do you read it, and how do you set it? So I made two small interactive tools, based on the original factory leaflet.
Tool 1, reading: press А for the time, keep it pressed for the seconds, press Г for the date and day of the week. The red display lights up and goes dark again, as on the watch.
Tool 2, setting: the three recessed buttons (the ones you press with a toothpick so you don't scratch the case), minutes, hours, date, and the seconds reset on the radio time signal. Hold a button and the digits climb, like the real module.
Both work on a phone.
The rest of the article covers the 1972 American Pulsar that inspired it, the Pulsar semiconductor institute in Moscow where it was developed, the two case styles I have handled (cushion and the fluted "Terminator"), and a 1981 passport showing the retail price: 121 roubles, around two thirds of an average monthly wage.
I also say plainly that this is fragile 1970s electronics. It is very hard to repair and it can stop working at any time.

If you spot a mistake, tell me and I will correct it. I would also like to hear from anyone who has the other case variants.
