The Vintage Wrist Watch Company has dated this piece to the 1900s.
You will see in the photo that there are two empty screw holes at the edge of the movement… in this instance, these retaining screws are not required as the movement is screwed into the threaded ring that sits around the movement; this is something we have never seen before.

The watch measures 46mm diameter excluding the winding stem and the loop. The case is 935 silver so slightly purer sterling silver, and there are Continental hallmarks together with the case maker’s mark for François Borgel.

Borgel was a very successful inventor and business man, and his company became one of the most important watch case manufacturers of its time. He advertised his screw watch case, such as this example, as "imperméable", which means that he considered his screw case to be waterproof . Early adopters of the Borgel screw case included Longines and IWC. After François Borgel’s death in 1912, the business was carried on by his daughter Louisa. As with any vintage watch, however, strongly advise that it is kept away from water and moisture.

Alongside the marks, there is also a brevet (patent) number 4001 which relates to an 1890s patent by Borgel for a new case design.
The case is in good condition, just light surface marking but nothing too serious at all.

The acrylic lens is in good condition.
The dial is in lovely condition with original pin-set blued steel hands, a subsidiary seconds dial and outer minute markers.
The watch comes with a silver double albert, with each chain measuring 19cm long. The clasps are hallmarked for 1927 and each of the links has the lion silver mark. There is also a silver fob with rose gold wash detail. The fob is also hallmarked for 1927 together with a maker’s mark for the Birmingham silversmith Herbert Bushell. The chain and fob weigh 23g.
The watch comes in a new presentation box.
