Help Needed: Breitling 806

Hi everyone,

I just won my first Breitling. It's a 806 and I've been searching for one for a long time.

Could you please let me know what you think about this watch? It's looks fine to me and the seller is a reputable seller. But I want to make sure all is good with this watch:

Many thanks in advance!
