The Vintage Wrist Watch Company has dated this piece to the 1910s.
Antique silver Longines trench watch, 1918.
The watch has a Longines calibre 13.34 18 jewel movement which is working nicely.

The watch measures 35mm diameter excluding the winding crown and the articulated lugs. The case is sterling silver and there are hallmarks inside the case back for London (import mark), 1918, together with a case maker's mark for François Borgel. He 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. Despite the Borgel case, this watch, as with any vintage watch, should be kept away from water and moisture.

The case is in lovely condition for such an early piece, a little tarnishing to the back and light surface marking but nothing serious at all.
The lens is in lovely condition.
The dial is in very nice condition. Originally there would have been luminous detail to the pin set hands and numbers but this has been removed over the years.
The watch has a later leather strap which has signs of age but is absolutely fine to wear... we can fit a new leather strap if preferred.
The watch comes in a new presentation box.
