It is difficult to work it, it is unpredictable and expensive, but the result is worth it. Titanium is called «winged» metal for a reason: it is widely used in aviation and aerospace engineering due to its lightness, durability and resistance to environmental influences.
Titanium watches are almost weightless and feel warm to the touch because of low thermal conductivity of the metal. Antimagnetic properties of titanium cases do not let the watch movement disrupt. Those caring about their health will especially appreciate how hypoallergenic this metal is.
