Tissot “Sytal”

European Watch Clock and Jewellery Fair 1974 BF 204
The functional look: a perfectly legible traditional dial and black chrome case water-resistant to 3 atmospheres (a depth of 30 metres). The movement itself has equivalent characteristics: it is made of the inalterable material Tissot has introduced under the name ’Sytal’ (“Systeme total d’autolubrification” = Fully Self-lubricating System), requiring no maintenance whatsoever.
