Vintage 70s Rado DiaMaster 10 Automatic Day Date Square Hardmetal 37mm Watch Box

About this watch

A bold and rare 1970s Rado DiaMaster 10 with a geometric square "TV" case. The broad, mirror-polished hardmetal case front frames a small square dial with a textured off-white finish, black-inlaid applied square markers, faceted steel hands, the red Rado anchor emblem, and a day window at 2 o'clock with a framed date at 4.

The case measures approximately 37mm wide by 42mm lug to lug and continues into an integrated multi-link stainless steel bracelet. The screw-down steel caseback is engraved DIAMASTER 10 around the Rado seahorse "Water-Sealed" medallion. It comes with its period presentation box stamped Al Ghazali in English and Arabic.

Brand heritage

Rado grew out of Schlup & Co., a movement workshop founded in Lengnau, Switzerland, in 1917, and began selling watches under the Rado name in the 1950s. Its trademark is the small anchor on the dial, which on automatic models is mounted so that it can swing freely.

Rado became known as the "Master of Materials" after launching the DiaStar in 1962, promoted as the world's first scratch-resistant watch thanks to its hardmetal (tungsten carbide) case and sapphire crystal. Through the 1960s and 1970s its bold automatic watches were especially popular across the Middle East and Asia.
