Yesterday I received this stopwatch. On the front side nothing remarkable: just an ordinary early Heuer stopwatch. I don't know exactly which type but in the 1945 catalogue contains picture of the back of what is called the 900-929 which is very similar. Serial on the case is 265xxx and on the movement 262xxx which is in line with others I've seen. The back is more interesting because it has an inscription: KNIL 227. The abbreviation KNIL is the Netherlands (where I live and acquired the stopwatch as well) used for Koninklijk Nederlands Indisch Leger or Royal Dutch Indonesian Army. This army was discontinued in 1950 when the Netherlands lost control of Indonesia and became an independent country. In the caseback are 2 inscriptions: TD2146 whereby the D might also be a P and the 1 might be a slash. If TD it might mean something like Technische Dienst (Technical Service). The other inscription looks like 2271/81. Handwriting looks slightly different but not easy to say for sure. All by all a nothing special but it might be a real KNIL used stopwatch!
