RADO 70's DIA STAR / Cal.1858

Introducing the Rado Diamond Star from the 1970s .

The "Diamond Star", released in 1962 , was the world's first ultra-hard case model made of tungsten carbide.

Tungsten carbide is much harder than stainless steel and is highly scratch-resistant, meaning it is less likely to be scratched even by minor impacts.

With the processing technology at the time, it was difficult to reproduce sharp lines and edges, so no one was interested in it as a material for watches.

However, Rado noticed this and released the Diamond Star, which features a distinctive oval bezel made from this material.

In addition to using new materials, the world was astonished by its unprecedented, cutting-edge design, and Diamond Star became an instant hit.

In contrast to the case that shines brilliantly like a jewel, the Diastar has a subdued, heavy black dial.

The ultra-hard case made of tungsten carbide remains scratch-resistant even after more than 50 years.

The design is also distinctive, with its cute, round egg-shaped form covering the strap connection area, eliminating the seam between the watch and the strap, highlighting the beautiful oval shape.
The unique case design will catch the eye of everyone who sees it.

Sapphire crystal glass is used for the windshield.
Sapphire crystal glass is not only highly transparent, but is also made of the same scratch-resistant material as the case.

The glass has fine vertical cuts, and when light hits it it gives off a beautiful, sparkling luster reminiscent of a chandelier.

The dial design is also distinctive, with the calendar, which is usually located at 3 o'clock, placed at 6 o'clock.

Instead, the pet's name is printed at the 3 o'clock position and the Rado logo is printed at the 9 o'clock position.
At the 12 o'clock position is Rado's iconic anchor logo against a red background.

All watches sold in our store are internally inspected by a professional watch mechanic upon arrival and are only sold after being determined to be genuine, so you can use them with confidence.

When you purchase a watch, we will attach a new leather strap to it when you deliver it to you.

A special case for the watch will also be included with the shipment.

Please be sure to read the following information after purchasing an antique watch.

When selling antique watches at RESUME, we do not immediately hand over the watch to you upon receiving your order. Instead, we ask a professional craftsman to overhaul it (hereinafter referred to as OH) and deliver it to you after the OH is completed. (This takes about 1 to 2 months.)

A professional craftsman with first-class watch repair technician qualifications will completely disassemble your watch, replace worn parts such as the internal gaskets, clean it, oil it, and perform a thorough overhaul, maintaining it to a daily accuracy of about ±1 minute.
When we deliver the machine, we will also send you our own overhaul certificate, which shows what kind of overhaul was performed, as well as photos of the machine being disassembled and maintained.

Of course, due to the nature of the product itself being a second-hand item, there is no guarantee that it will never break, but we ask for your understanding that we take this approach so that you can enjoy the original performance of the watch and use it with peace of mind in the future.

When you purchase a product, we offer a one-year warranty depending on the model. Even if the warranty period has expired, we will properly repair the product, but there will be a fee. If there is no repair shop near you, please feel free to contact us.
