The Vintage Wrist Watch Company has dated this piece to the 1910s.
The watch has a stem-winding movement, an IWC 53, which is working nicely.
This particular movement has the Stauffer & Co mark, together with the Peerless name which confirms that the movement was made by IWC (International Watch Company).

The movement also carries a Swiss brevet (patent) number 31457 which relates to a patent filed on 5 November 1904, with the applicant being Fabrique d'Horlogerie de J. Rauschenbach and it relates to the crown and ratchet wheels.

The movement also carries the serial number 631851 which dates it back to around 1917/18.
The movement is protected by an inner hinged cover.
The watch measures 50mm diameter excluding the winding stem and the loop. The case is silver and there are hallmarks inside both of the case backs for London (import mark), 1917 with a sponsor’s mark for Charles Nicolet (of Stauffer).

The front of the case is in good condition. The hinged case back has some slight unevenness.
The glass lens is in good condition, as is the dial with original pin-set blued steel hands, a subsidiary seconds dial and outer minute markers.
The watch comes in a new presentation box.
