Titanium – the material of the future

High-performance turbine blades, aerospace components, implants, sports equipment and many other high-tech products are made of titanium these days, a trend that is becoming increasingly popular. 

Hardly any other material combines so many outstanding characteristics: extremely high strength coupled with low weight. Corrosion resistance even under extreme conditions. A surprising ability to shield against electrical and electromagnetic fields, plus extensive resistance to eddy currents. What is more, it is anti-magnetic and completely anti-allergenic.

Titanium boasts strengths that lie in the same range as tempered steels and retains these properties even at temperatures of approx. 200 to roughly 630 °C. Depending on its alloy, it has a tensile strength of between approx. 300 and 1150 N/mm2. This is impressive and far higher than that of steel. With a specific weight of 4.51g/cm3, titanium is also only around half as heavy as crude steel.

Furthermore, titanium has what is known as a self-healing ability. If its surface is damaged, a wafer-thin, invisible yet extremely resistant titanium oxide layer forms immediately, protecting the material beneath. These many special properties, which seem almost “supernatural”, are also what gave this metal its name – which is derived from the Titans, a race of deities worshiped by the Ancients Greeks.

This metallic element with the atomic number 22 was only discovered in 1791 by William Gregor as a constituent of ilmenite. Pure titanium was first produced in 1910, and only made ready for commercial use in 1940 with the aid of the Kroll process. In its metallic form, it is a relatively new technical material, in other words. Ever since, its popularity as a high-tech material has soared, and it is justifiably described as a material of the future.

An expensive but superior material in the watch industry

The disadvantages of titanium are primarily its high price and the fact that it is difficult to process. As it wears normal tools out very quickly, it can only be processed using special equipment. Extracting titanium is a very complex and therefore expensive matter. It was long thought that titanium was not suitable for manufacturing watch cases because it is so difficult to shape. It was not until the end of the 1980s that a renowned Swiss watchmaker succeeded in producing a wristwatch with a titanium case. Ever since, it has been regarded as an expensive but superior material in the watch industry.

Besides the outstanding technical characteristics of this metal, connoisseurs also value its refined and warm colouring. The “Titan-1” was our first wristwatch to feature a titanium case, and for 20 years was our unchallenged bestseller. It was only thanks to the use of titanium that such a slim and lightweight watch could be produced. The Titan-1 won a total of seven international design awards for its impressive overall performance.

BOTTA design has already been using titanium for its watch cases since 1991

Our current collection also features a number of watches with an exclusive titanium case, for example the UNO titan, the UNO titan anniversary edition, the NOVA titan and the TRES, each with a case diameter of 40mm. The recently-released TRES 24 titan, a 24-hour multi-hand watch with a diameter of 40mm, also boasts an all-new and highly attractive case made of this refined lightweight metal.
