We are proud to offer Excellent Preserved Important Longines: Quartz-Cybernetic Tuningfork, Ultra-Quartz.

What we have? Well, one tuningfork-engine humming at 170Hz, 19 resistors, 14 transistors, 7 capacitors and a quartz crystal vibrating at 9'350Hz -- the latter controlling the first mentioned: Ultra-Quartz, indeed.

Yes, some watches are crazier than others and here is one that was so far from the future in 1969 that it makes you smile even today.

Needless to say that both frequencies (170Hz and 9'350Hz) are audible, yeah.

The case is in like-new condition, the crystal and the dial as well -- the latter showing the original aged tritium. Unique like this.
