: Welcome to the forum !
: A Siffert with a 142xxx makes for a very early execution. This
: would most likely be a ridged hour marker version with a Cal.11
: movement and unpainted stainless hour and minute hands. These
: particular early executions are considered quite desirable &
: accordingly are not cheap.
: A picture would help a lot to spot any errors or problems. Feel
: free to post a picture here on this thread or email me directly
: if you'd like advice.
: Good luck - Darren

Thank you for the info Darren. Unfortunately I do not know how to upload a picture onto the forum. However I was able to e-mail you a picture of the Siffert for further analysis. If you know how to upload the picture I e-mailed you to this thread please feel free to post it here so other people can weigh in.
