Hia again to all Paneristi guys,
as a newbie I have a couple of questions for you
1. Why Panerai crown protective device in some models says
REG. and T. M. on it and on some others not?
2. What is the difference between OP II and OPXI caliber
in terms of accuracy and reliability.
3. Many sellers say for their watches that have
"plenty of amplitude" . What they mean by that?
4. If a caliber for example OP XI has a swan neck,
what's the advantages on this cal?
That's for the beginning...
Thanks for reading and your patience
