Mar 11, 2014 The other poster's watch was a C.W.C. Co watch with a serial number of 180825 which you said was probably produced around 1887-1888. I don't have quite as much detail about this watch, but inside one cover are the letters C.W.C. Co and the number 581555. Over near the side is scratched the number 19244 or 19744 in TINY hand-scratch. This blog entry is on the markings on the case back of the G10 field watch issued by the British Ministry Of Defense. This is based on my readings and on the case back of my small collection of G10 watches. I have G10 watches made by CWC and Precista.
