The watch is rare in very good condition.

It seems that everything is original including crystal with a magnifying glass and the crown (litttle worn from the front). 

Very attractive domed dial in great condition. 

20 microns gold plated case also in very good condition.

Caliber Buren 1006 - mechanically flawless, everything works correctly, holds time very well. The service history is not known to me.

Only what you can attach to is not simultaneously drilled holes for spring bars in the lugs (see the last 2 photos), lugs are not bent. After putting on the belt, it does not catch the eye, probably the new owner would only notice it after removing the belt. However, I prefer to mention it. 

Maybe that's why the watch is in such good condition because it was not sold in the first phase of life - by this factory defect, who knows?

The watch will come on an unused vintage strap from photos.
