I have a Jaques Lemans 1-1170 Automatic Chronograph
with a valjoux 7750 movement. I have been trying to
find some info about it (how old, what it's worth,
etc.) but nobody has heard of this model. You seem
like a very knowledgeable group and I hoped you could
shed some light for me. I have sent some photos.
Thanks for any info you could give me.
