Hello,
Happy New Year!
Portuguese Chrono-Rattrapante had the split second function with manual winding.
Anyone can tell me the proper operational of the spilt second function because I could not find the manual.
In addition,
-The approximated no. of turn for full winding.
-How'long for the normal running e.g 48hr? Or
-Is there many replica in the markets?
-what's the last year of the production?
Many thanks.
Lam
I've uploaded the manual in PDF format here:
www.gregsteer.net/IWC/Manual/Ref_3712.pdf
Can't comment on how many replicas are in the market but I'd be surprised if there wasn't one.
The Ref 3712 was last in the 2004 catalogue.
Cheers from the cellar
