More information about this movement:
Introduced in 1910, the Longines 13.34 movement was used in many Longines wristwatches during the Great War. Often, like this one, they do not carry the name Longines visibly, but they are quite easy to identify. The calibre number 13.34 is stamped on the bottom plate and is visible next to the escape wheel. If you click on the picture and get an enlarged view you should be able to see this just inside the case screw next to the copper coloured dot that is the end of a dial foot. You should also be able to make out the B & Co. mark of Baume & Co., Longines agent in the UK for many years. Failing that, the shape of the plates and bridges is very distinctive — although there is also a variant with the same barrel bridge shape but the three individual cocks of the third, fourth and escape wheels fused into a single bridge.
