Rado, a watch brand based in Lengau in the Swiss canton of Bern, has been part of the Swatch Group since 1983 and produces watches in the upper price segment. Rado watches are available in over 5,000 retail outlets and over 70 stores. The brand is known for its research in materials science. Several hundred thousand watches were produced in 2018.

Rado was founded as Uhrwerkfabrik Schlup & Co. in 1917 in Lengnau by the brothers Ernst, Fritz, and Werner Schlup, and in its early decades operated exclusively as a producer of ebauches. In 1937, Rado Watch Co. Ltd. was founded as a subsidiary within the same company; another wristwatch brand produced by the Schlup watch factory from the early 1940s to 1957 was Exacto. From around 1958, only watch models were offered under the Rado name. The DiaStar, developed in 1962, is considered the world's first scratch-resistant watch. From 1962 to 1968, the Captain Cook MK1 diver's watch, with a depth resistance of 220 meters, was produced in small quantities of just 8,000 units. From the mid-1960s onwards, the threat from low-cost manufacturers from Asia steadily increased
