After WWII the MoD procurement regulations expressively asked the manufacturer to engrave the markings and the serials. It was part of his duties (at least with the RAF). And so did IWC and JLC as well (That's the reason, why the markings of the JLC and IWC Mk. 11 look so different). In the first year of issue one block of Serial Nos. was reserved for IWC Mk. 11, another one for JLC Mk. 11. Therefore you will find no 1948 JLC Mk. 11 with a SN lower than 2,100.The situation had been different in the period from 1940 to late 1944: The Swiss manufacturer exported their watches via train or truck via France, which was controlled by the Germans. The Germans wouldn't have allowed the watches to pass in case they would have known these watches were navigational wrist watches for the RAF. So the markings were done after the watches arrived in England.
