The Vintage Wrist Watch Company has dated this piece to the 1900s.
The movement is signed with the IWC Probus Scafusia emblem, Probus Scafusia is a Latin phrase mean ‘good, solid craftsmanship’, a motto registered in 1903.

The movement also carries the serial number 505557 which dates it back to around 1910, together with the brevet number 31457 which relates to a 1904 patent for ‘device for limiting the winding of barrel watch movements’.

This particular watch was made for the German market, hence the letters V and N on the regulator for Vorrücken and Nachlassen (faster and slower).
The movement is protected by an inner cover which a little scratching where it has been opened in the past.

The watch measures 50mm diameter excluding the winding stem and the loop. The case is 800 silver and there are German / Continental marks inside both of the case backs, together with the IWC Probus Scafusia emblem.

The case has rose gold wash detailing around the edge of the case back and bezel and, unusually, it is still in lovely condition… so often this has worn off over the years. Nice crisp engine turned detail to the back and a central vacant cartouche.
The glass lens has small marks across it.
The dial is in beautiful condition with original pin-set ornate hands, outer minute markers with red numerals and a subsidiary seconds dial.
The watch comes in a new presentation box.
