Hi Ben
Due to the fact that there is no definitive resource on the Heuer Diver 1000 series we are at the beginning stages of this process. We have prepared the preliminary reference table which I have sent to you via email. This process is well advanced on most of the other Heuer models from the 1960's onwards e.g. Autavia, Carrera, Monaco etc. They have been catalogued, compared and discussed in great depth and the finding published on the OTD site for all to share. Many of the forum members are now more that capable of authenticating every detail of these watches thanks to the sharing of information via this medium. We are just beginning this process for the Diver 1000 series and your watch is a good example of the process that needs to take place in order to achieve a definitive resource.
On early examination, it seemed quite clear to some including myself that the lume on the hour markers was different to the norm. The norm being most examples from the period showing similar lume pattern i.e. flat lume covering most or all of the hour marker. Now that you have discovered a second example of this new pattern it could mean that it is an original factory finish. It could also mean that it is a restoration.
I hope that we can get some contributions on this subject from those more experienced than myself and those with first hand experience of dial restoration. In my opinion, the lume on the second example (not your watch) looks like it has been applied by hand giving a raised appearance. Your watch has traditional flatter apearance but smaller diameter than normal. On all my examples the lume is flat and covers most of the hour marker.
Lets see what other have to say and keep the dialogue going.
regards
Paul
