Vintage 1951 Eterna-matic 33mm Watch

All original Eterna-matic 33mm Watch, circa 1954

This all-original, all stainless steel watch dates back to 1951. It's the first self-winding watch to employ a ball bearing rotor. This watch is water-resistant and shock-resistant making it very modern in many respects. The in-house mevement is based on the "1080" ETA and was found as the base calibre for a manual wind, an early "bumper" automatic and this last rotor model. All Swiss unit from beautiful Grenchen. Eterna has an illustrious and innovative history worth exploring. Eterna was founded in 1856.
