It was officially introduced t0 the watch world around 1973/1974 but after the first run was manufactured, the caliber wasn’t produced again until 1985, thanks to mechanical timepieces gaining popularity once again. The watch movement 7750 was partially designed on a computer – a first for the watch industry. The movements we offer are made in Switzerland by ETA and are brand new.
