CHRONOSPORT UDT SEA QUARTZ - Helmut SINN

Extremely rare and eaely CHRONOSPORT UDT SEA QUARTZ by Helmut SINN. This watch comes in very rare gold plated version. The plating is in TOP conditions for a watch almost 60 years old. More important this IS one of the very very rare examples working perfectly. Case Back has some sings of wear. We installed a new crystal and original to this model movement holder - an important piece with function. The holder is in perfect conditions. Comes on a generic black leather strap.
