Temporis Chronograph Ref. 621317 from the 60´s

Extremely rare Temporis Chronograph ref. 621317 in very good and completely original and untouched condition from the 60´s. The case is showing only minor signs of wear and the gorgeous dial and hands set are mint condition. The service history is unknown, but my watchmaker has just checked the movement (Landeron 149) and is running perfectly well.
