Quiet rich old man scent

I sat next to this old, rustic, quiet rich looking old man at the park, and his perfume was so good but I was too shy to ask him what it was. Any ideas what scents an old rich man in Europe would be wearing? Was not spicy, more clean but rich and like a very expensive old house with loads of books by the sea. Any ideas of what it could be, just to give me a starting point of what to try first at the perfumery store this week in search of this amazing scent!
