Can somebody please tell me which IWC this is?
I received it from my grandpa which just passed away. We found this in his closet.
We don't think the box matches the watch, since I couldn't find anything related to IWC Referenz 5001.
Thanks for your help.
Hello and welcome to the forum.
Indeed, it is not a ref 5001, It looks like the Portugieser Chrono
Yes i know it's a portugiesier chrono, but which model?
It appears to be 371480
But the black rehaut/bezel is unusual for this silver dial.
Are there gold hallmarks visible on the caseback?
