This automatic, two-tone day / date wristwatch apparently dates back to the 1980s. It has a 34mm case with gold dial. On the case back it says: Water Resistant Automatic Incabloc Stainless Steel Swiss Made 418-439. The dial says Automatic, Swiss made. I doubt whether it is still water resistant. Original plastic crystal has some defects. The bracelet is not original but signed Certina.
