UK POSTAGE ONLY FOR THIS ITEM
The watch has a 17-jewel bumper automatic movement, calibre 332, which is working nicely.
Later automatic watches have the fully rotational rotor.

The movement is fully signed and it has the serial number 12,250,085 which dates it back to 1950.
The watch measures 36mm diameter excluding the later winding crown and the lugs. The case is rose gold filled, a generous 80 microns thickness. The condition looks good to the naked eye. On closer inspection there is some rubbing around the bezel and some general light surface marking.

The stainless steel screw-on case back is signed inside with the Omega logo, and also the case reference 2493-3 which is correct for the calibre 332.
The lens is in lovely condition.
The signed dial is in its original finish with original hands, subsidiary seconds and inner minute markers. There is some age related marking across the dial.
The watch comes on a later leather strap with an after market Omega buckle.
The watch comes in a new presentation box.
