Purchasing a Patek from Watchbox/Govberg online?

[italiafan]

Hi All,
Sorry if this has been beaten to death, was looking through a search of same and didn’t find anything that stood out in first couple pages. I have never bought a watch online, much less a Patek, a little nervous doing so.
Thought I’d ask anyway....

I’m contemplating buying a Calatrava off Watchbox, which I understand is Govberg.

Any issues concerns come to your more experienced minds?
