Hello,
Unfortunately, the IWC website doesn't provide me with satisfactory information based on my serial numbers.
I have
a Portuguese 3712-02 (from 2000) and
a Portuguese Regulateur 5441-01 (from 2011).
i habe two diffferent folding clasps.
1x with IWC logo
1x with Probus Scafusia logo
I read somewhere that the folding clasp with the Probus Scafusia logo has only been available since 2011. Is that correct?
If that's the case, it would clarify the assignment to the respective watch for me.
I would be very grateful for your help.
regards
ulrike
