This is an original 80s Tissot F1 Formular1 Sensorquartz with touch bar. The movement was co-developed jointly with OMEGA. From the Caliber 1640 only 15.000 movements have been produced all together in 1980-1984. Tissot had a good stake into the F1 time keeping at this time and also developed limited versions of this model with e.g. LOTUS. The watch is in very good conditions with only little wear marks to case and bracelet and crystal. Finding this model working and not heavily used is rare . Most important the original Tissot bracelet comes along - missing at most offers. The bracelet fits 18-18,5cm wrist size. Collectors Conditions.
