Inspect the vintage Rado watch dial with a jeweler's loupe. At the top of the dial under 12 o'clock, the name "RADO" is embossed in raised capital letters. Models from the 1950s have "RADO" painted. The letters are grouped tightly but evenly spaced.
Examine the red and silver anchor symbol on 1960s and later models. The anchor should rotate. If it's fixed, the Rado may be a fake.
Examine the acrylic crystal on pre-1980s models. A tiny anchor logo should be in the center. A missing anchor may indicate a watchmaker replaced a damaged crystal at some time.
Examine with the loupe the model designation. A Purple Horse model is accompanied with a horse emblem. However, some counterfeits may use a Gazelle emblem from the Gazelle model on a Purple Horse model.
Inspect the crown, which is the slotted twisting knob on the case edge at 3 o'clock. A raised letter "R" is featured on all models manufactured until about 1958. A raised anchor symbol is used on post-1958 models. Keep in mind that it took Rado a couple of years to make a full transition from an "R" crown to an anchor crown. It's also common to replace crowns over the years. Finding a generic crown on an older Rado is common.
Use a case blade to pry open a Rado with a snap case back. Use a rubber jar opener to rotate counterclockwise a screw case back. Remove the case back and inspect with a jeweler's loupe the movement. The movement is a small engine that regulates the timing of the watch. All post-1957 Rado movements are clearly stamped with the "RADO" logo. All movement parts on the movement should have the same discolored aging on older models.
Examine the stainless steel bracelet. Original Rado bracelets have the "Novavit SA" triangle logo stamped on the inside. Replacement bracelets have no such logo.
