I am selling this truly cool Certina Certronic in very good condition. The watch is completely original and it looks very good for its age, only very minor signs of wear. The dial is in perfect condition. Photos are part of the description. The movement is a tuning fork movement with the calibre number Certina 29-151. Connoisseurs will surely see that it is a movement originally made by Bulova, but that these movements are also often found in the Omega f300Hz. Case diameter: 37.5 mm Strap length 20 cm or more, there is a spring mechanism in the clasp which allows the strap to attach to your wrist. The glass is made of plexiglass.
