This is a well-designed and pretty little ladies wristwatch from the mid 1960s. It has a neat 9ct gold case which measures 21mm x 21mm with a lug-to-lug measurement of 27.25mm.
The front of the case is 9ct gold and is in good condition, with the case back being one solid piece. The inside of the case back has peerlage finishing and is signed “SD”, the makers mark for Dreyfuss & Co, owners of Rotary. It has English hallmarking for 9ct gold from London assay office, with the date letter “k”. This puts the watches production at 1965.

The crown appears to be original and is in good condition with only light surface scratches.
The watch is on a new old stock genuine leather strap for fixed lugs, non-Rotary.
