Swiss Watch Fair 1967 BF 74
The bold modern case of this new Optima watch incorporates two systems of protection : a) the “Suspense” shock-protection system whereby plastic cylinders keep the movement suspended inside the case and b) the “Super compressor” water-proofing system which prevents condensation and distorsion of joints due to excess pressure This watch is also equipped with a wide-aperture day and date calendar (name of day in full). (OPTIMA “V.I.P.”)
