I came across this extract of the archives for a recent listing for a RAAF G6B/158 being sold in Japan and I thought I'd get one for my own RAAF G6B/158, after all they are issued without charge by Longines (Lesson here for Omega ) Anyway, below is the response from Longines - what a shame. It would have been nice to get one to track its history to the RAAF. I can see their position. It really doesn't make a lot of difference I guess. However, I thought the extract would be for how it left Longines factory not what happened to it later as I am not asking for them to attest to its changes or authenticity of any transformations since 1942. Oh well...would have been nice. This is the response from Longines Branding and Heritage: "Thank you for your message and the information provided. Nevertheless, even after having spent the last two days in our archives, we still are unable to issue you with an extract. Indeed, there has been a recent change in our policy about extract delivering. Therefore, if the case, the movement or the dial doesn't match our records, we will no longer issue an extract. But this does not mean that your watch is (sic) not a genuine officially modified watch for the Australian Air Forces. It simply means that the watch does not look like the piece it was on leaving the factory and that therefore, we can't issue this paper. We hope this information will be of help to you and remain at your entire disposal for any further information you may need." My own (gratuitous) photos of this amazing watch.
