Andrew's recent acquisition made me wonder how many variations exist. When I browsed the archives I could only find reference to ref. 1829 and 1830, including a military style version. Also a distinction between an automatic and automatic SL was mentioned. Unfortunately the pics did not pop up (too long ago).
Could anyone, if possible, please clarify:
1. what models are known: reference numbers, movements, dial variations.
2. what the difference between the regular and the SL model is.
3. During what period the watches were produced. (won't ask for production numbers as they are unknown).
4. (if allowed) the average street price.
Any pictures would be appreciated as well.
Thank you!!
Peter
