Description:
In 2002 Rado celebrated the 40th anniversary of the introduction of the Diastar series, the original scratch-proof watch with case components made of tungsten-carbide. Among several re-issue models made at the time, Rado produced 600 Diastar chronometers with white dial, blue hands & markers, and the designation 40 on the dial to indicate the anniversary. The case features a display-back—something not often seen on Rado automatics before this period—which is engraved with the dates 1962-2002 and the individual series number of the watch. The numbered chronometer movement, ETA Cal. 2836-2, is gold-plated and decorated with perlage and côtes de Genève.

The original bracelet with signed Rado clasp is present on this watch. A period Rado box is present, but it is believed not to be the correct one.
