The warmth, lightweight, and rich grey color or titanium are responsible for its increasing popularity for wristbands and watch cases.
Titanium is available in pure or alloyed form, but there is no reason to increase its strength with alloys for the purposes of jewelry, therefore the purest grade of titanium is the most desirable for this application.
It is the perfect material for individuals that suffer from nickel sensitivity. Do make sure that the watch cover (the underface) is made of titanium if nickel sensitivity is an issue in your decision to purchase a titanium watch.
