The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a Swiss 17-jewel Landeron 248 hand-winding movement which is working nicely.
The watch measures 37mm diameter excluding the winding crown and the lugs.

The lens is in good condition too.
The signed dial is in its original finish with dauphine shaped hands and two subsidiary dials, one for constant seconds and the other records up to 30 minutes. The chronograph is operated by pressing the top button to start and the bottom button to stop and re-set to zero.

The dial is signed Sada. This brand name was first registered by the Swiss company Montres Sada SA in 1944, and the name was registered again by the same company in 1949 but this time with the addition of the mosque logo (Sada Mosquée).
A new leather strap has been fitted.
The watch will be sent in a new presentation box.
