The movement is stamped MuDu, 25 jewels, Swiss.

The watch measures 32.5mm diameter excluding the winding crown and the lugs. The rose gold plated case has light surface marks but overall is in nice condition for a 1950s piece. The screw on case back is stamped MuDu, Doublematic, stainless steel back, Swiss made, automatic, incabloc and waterproof although, as with any vintage watch, I would not rely on it being waterproof.

The lens is in nice condition.
The dial is signed MuDu, Doublematic with Swiss made at the bottom. It is in lovely condition with just the lightest of marks. It has its original hands and a date display
A new brown leather strap has been fitted.
