The Rado Diastar is a popular watch model that was first introduced by the Swiss watch brand Rado in 1962. At the time of its introduction, the Diastar was a groundbreaking watch due to its use of innovative materials, including tungsten carbide and sapphire crystal.
The Diastar was designed to be a scratch-resistant watch that could withstand the wear and tear of daily use. The watch featured a hard metal case and a sapphire crystal that was resistant to scratches, making it one of the most durable watches of its time.
Over the years, the Rado Diastar has undergone several updates and changes, but it has always remained true to its original design and concept. Today, the Diastar is still a popular watch model, known for its durability, style, and innovation.
Rado has continued to innovate with the Diastar over the years, introducing new materials and technologies to make the watch even more durable and reliable. For example, in the 1980s, Rado introduced the Ceramica Diastar, which was made entirely of high-tech ceramics, and in 2016, the brand introduced the HyperChrome Ultra Light, which features a case made of ultra-lightweight silicon nitride ceramic.
Overall, the Rado Diastar is a watch model with a rich history of innovation and technological advancement in the field of watchmaking. Its unique design, durability, and scratch-resistance have made it a popular choice among watch enthusiasts and collectors around the world.
