Description: This is the uncommon chronometer version of Rado's original Diastar design. Made ca. 1970s, it is very much like the 1962 Diastar which also featured a segmented, applied hour chapter, date window at 3:00, and the oval Diastar scratchproof case.

The case front shows no wear, though the back has some minor marks. The movement is keeping accurate time; service history is unknown, but the movement is clean; date functions properly at midnight.

The original bracelet with signed Rado clasp is present on this watch. Original inner and outer boxes are present, as is a Japanese-market hang tag with MRSP of 130,000, which is consistent with advertising of the period.
