The Vintage Wrist Watch Company has dated this piece to the 1950s.
The movement is stamped automatic, 25 jewels.

The watch measures 33.9 mm diameter excluding the winding crown and 41.6 mm high including the lugs. The rose gold plated case has light surface marks from use and some wear to the lugs although it has a good vintage look. The screw-on case back is stamped automatic, stainless steel back, incabloc, Swiss, antimagnetic and waterproof although with any vintage watch I would not rely on it being waterproof.

The lens is in good condition.
The dial is signed Oebra, automatic, 25 rubis, incabloc with Swiss at the bottom. The dial has faint surface marking although hardly noticeable, but overall it is in nice condition for its age.
The watch has its original hands.
A new black leather strap has been fitted.
Price includes worldwide postage.
