We mentioned previously the imposing dimensions of this watch. What we omitted to mention, however, was the fact that this watch, surprisingly, is extremely easy to wear. This is due to the case being made entirely of titanium. The metal titanium has two important characteristics. First, it is extremely light (this lightens the entire mass of the Z-Sport watch and makes it much easier to wear than most of its much smaller rivals) and second, on contact with the skin it gives off an extremely pleasant sensation and this is because titanium is silk-like to the touch – a quality that is unique to this metal. This makes the Z-sport watch perfectly tolerable even to individuals who suffer from dermatological allergies to gold and nickel. In effect, it is for this very reason that titanium is regularly used for internal prostheses, which are used frequently for implantation in the human body.
