An entirely new conception of integrated design : the case is slipped onto a one-piece bracelet and fixed centrally by means of screws (a recess in the bracelet ensures that the case is held firmly against the wrist). With this system, it is simple to interchange the chain mail bracelet in braided solid steel wire and the water-resistant hydrocaif or genuine rubber strap. Equipped with a quartz movement, this man’s solid steel watch comes in two sizes. Water-resistant to 100 m. HR 900 high-resistance crystal.
