Eterna winding crown with the five ball bearings logo.

In 1948, Eterna introduced their automatic movement which contained five strategically placed ball bearings which made the movement very efficient and significantly reduced friction and resistance on the oscillating weight that wound the mainspring. This reduced the wear and tear on internal parts, increasing the watch’s accuracy and useful life. The watch was probably Eterna’s most famous and it was in fact so successful that Eterna adopted the image of five ball bearings as its corporate logo.

The lens is in good condition.
The signed dial has been re-finished at some stage. Original hands, seconds sweep and outer minute markers.
A new leather strap has been fitted.
The watch comes in a new presentation box.
