The IPJ 0612 digital sub-dial displays the current time (hours, minutes) via flip-up sheets. The clock mechanism is controlled by minute polarized pulses from the main clock (type ESH 3, EH 40, etc.). They are primarily intended for interior use in various buildings and operations (industrial areas, schools, offices, medical facilities, bus and railway stations, etc.). This type of subsidiary clock was one of the most widespread, and many of them (more or less) reliably serve in uniform time systems to this day. The IPJ 0612 watch is the last type produced using the flip-leaf technology. With the end of their production, the era of digital leaf clocks of the Pragotron brand has come to an end.

The item is sold in its original condition, nothing has been modified. They look very cool for a loft interior, suitable for collecting or just creating a retro atmosphere. They are fully functional, in the modern world they can control a simple circuit, for example Аrduino, which supplies them with 24 volt pulses every minute.

Given their age, they are in perfect condition.
