Roidor was a Swiss watch brand, likely operating as a smaller manufacturer or a "private label" brand during the mid-20th century, notably producing watches from the 1950s through the 1960s. These Swiss-made, often 17-jewel, mechanical timepieces were popular as commemorative gifts, frequently awarded for long service in the UK.
