The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a Venus 220 hand-winding movement, with 21 jewels, which is working well. The movement is stamped 21 jewels Swiss made.

The watch measures 30.5mm diameter excluding the winding crown and 38.2mm high including the lugs. The case is gold plated and there is some rubbing to the edges and tops of the lugs although it has a great vintage look. The case back is stamped with the Rotary wings and Rotary, stainless steel back, Swiss made, antimagnetic and waterproof although with any vintage watch I would not rely on it being waterproof.

The lens is in very nice condition.
The signed dial is signed Rotary, 21 jewels, antimagnetic with Swiss made at the bottom. The dial has faint surface marking although it is in nice condition for a 1950s piece.
The watch has its original hands.
A new dark brown leather strap has been fitted.
Price includes worldwide postage.
