The watch measures 50mm diameter excluding the winding stem and the loop. The case is 800 silver with a rose gold wash to the bezel and the perimeter of the hinged case back, known as galonne. The inside of the case back has the case makers mark RF for Rebetez Freres of Biel in Switzerland. There is also a sunburst effect to the back with a vacant cartouche below.

Overall the case is in good condition, just one slim 1cm flattened area to the side but not too detrimental.
The acrylic lens is in good condition.
The white enamel dial with sunken centre and sunken subsidiary seconds dial has a hairline crack running between the centre and number 4 but otherwise is in good condition with blued steel hands and outer minute markers.
The watch will be sent in a new presentation box.
