Flzal,

If those data are available I do not have them. Also, in the previous posting I failed to mention that Heuer produced two register movements using the 10-½ lignes Valjoux 69. I am confident they used other calibres as well. For instance, in Jeff’s article on the phony Targa Florio, there is a reprint of a magazine advertisement for a 15 lignes aviator’s watch. Can anyone identify the movement used for this watch? Universal and Lemania made the only 15 lignes chronograph I know of from that era. I suspect Heuer may have also produced movements based on other Landeron calibres, such as the 3, 39, or 52. I would be very interested to hear about any Heuers with these movements. I am not very familiar with later model production (60’s +). However, I have seen movements based on the 13 lignes Valjoux calibre 92.
