Swiss Watch Fair 1969 BF 50
Diving watch with automatic movement. The calendar is excluded on purpose in order to increase dial legibility. Notches prevent the turning bezel from moving in the wrong direction, to prevent any risk of error in diving time calculations. Dark blue concave dial. Hour-markers are placed on the inclined sides and give the model a technical appearance. All-steel case water-resistant to 20 atmospheres. Scratchproof crystal. (FELCA-TITONI)
