#Vintage rado diastar series

Most stainless steel alloys soften as they approach 1,000вЊ, whereas tungsten carbide withstands nearly thrice that.Д«ecause of its extreme hardness, shaping hardmetal into intricate shapes is a difficult proposition. It rates the same as sapphire, for example, on the Mohs hardness scale. Tungsten carbide is usually used for drill bits and other components that must endure high temperatures and pressures without deforming. What Is A Tungsten Carbide Or Hardmetal Watch? This was apparent in 1976вЂ™s Dia 67 GlissiГЁre, a square watch with a nearly edge-to-edge sapphire crystal over its face. Sapphire watch crystals had been around since the 1950s, however, no one had yet embraced them like Rado. Together with a sapphire crystal, this case protects an automatic ETA mechanical movement with a date display.ДЄ sapphire crystal protects the DiaStar 1вЂ™s dial, which is not unusual today, but was rare at the time. The case of the original DiaStar, still available today, is made from golden or silver-colored tungsten carbide, also known as hardmetal. This was distinct from вЂњscratch resistant,вЂќ since the hardest case materials in watches at the time were typically steel alloys.ДЄlthough steel is harder than gold and silver, it is soft and ductile next to what Rado had in store. When this watch came out, the company touted it as вЂњthe worldвЂ™s first scratchproof watch.вЂќ Where the brand truly took off, however, was with 1962вЂ™s DiaStar 1. The DiaStar: The First Scratchproof Watch

Out of these, the Green Horse and 18K gold Golden Horse that came afterwards are the best-known today.

At first glance it is very much a watch of its time вЂ“ there were (and are) many different models, but the ur-DiaStar has an immediately recognizable shape. The DiaStar is probably the single most memorable vintage Rado watch вЂ“ the company brought out the first one in 1962, the year of (among other things) the Cuban Missile Crisis, and the debut of Dr. One of the most interesting watches of the late 20th century is, to me, also one of the less appreciated, for various reasons (more on that in a minute) and itвЂ™s a watch that says a great deal not only about shifting tastes, but also about the march of technology and how itвЂ™s affected what we expect from watches right down to the present day. One of the interesting things about watch collecting is that it has all sorts of little archipelagos of design and mechanical innovation to be discovered, once you branch off from better-traveled territory.
