Beautiful silver dialed all steel automatic with the famous 25-651 26 jewel movement. The watch has not been polished and has the marvelous turtle back. The serial number 7950320 (the “2” is upside down, proving that the numbers must have been punched manually) dates this DS (double security) to 1969. The reference number of this model is 5801 300. Runs perfectly, but should have a service.
