Titanium is associated with outstanding achievements in aviation, aerospace, surgery, implantology, and other disciplines. The metal was discovered about 200 years ago, but not until 1980 did Ferdinand A. Porsche and IWC realize that titanium could also be used as a material for watch cases. The first titanium chronograph celebrated its market launch the following year. This metal unites all of the favorable properties of steel and aluminum. Titanium is very safe and secure, lightweight and sturdy. Titanium watches weigh only half as much as comparable stainless steel watches because this metal has a specific gravity of just 4.5 grams per cubic centimeter. However, titanium is equally hard or harder than steel and nearly 100 percent resistant to corrosion. Furthermore, this element is also unaffected by acids and alkalis and has highly appreciated antiallergenic properties. The insusceptibility of titanium watches to magnetic fields is another welcome attribute. A few minor disadvantages nevertheless exist: this brittle metal with a grayish shimmer is comparatively costly, difficult to process, and can be brought into the desired shapes only with the aid of extremely hard and exceedingly expensive tools that, unfortunately, quickly become blunt or worn out.
