Rado Diastar Original Watches - History Behind It Rado Diastar Original Watches - History Behind It | Page 5

The Diastar was first introduced in 1962 and was heralded as the
first scratch proof watch ever. It was a time when most of the
watches were made of gold or stainless steel. These watches
were prone to scratches and every premium watch company in
the world was looking for a material which would not scratch. It
was then that Rado opened its own metallurgy division and
came up with the hardest metal ever: tungsten carbide. It was
prepared by the fusion of tungsten and carbide at 1000
atmosphere pressure in a vacuum furnace. Moreover, the dial of
the watch was covered with sapphire glass to prevent any kind
of damages to the dial. It was the first ever watch to use
sapphire glass for its dial. It was all done in an age when nobody
even thought of using hard metals and sapphire glass in a watch.
The name Diastar hinted at the concept of Diamonds and stars
which was what Rado was aiming to achieve with this classic
piece of timeless wonder.
