A typical example of the “technical” type of watch whose popularity is definitely on the increase. This Rotary “GTO” model has all the characteristics of a diving watch and is water-resistant to 660 feet (or 200 meters). The turning bezel allows measurement of elapsed time and also, by using the scaled white ring on the dial face, the time in all parts of the world. Also available with simple turning bezel. Note the perforated bracelet. (ROTARY “GTO”)
