I remember when the Portuguese chrono was one of the hot watches - that ship followed HMS Panerai out of the dock.
I bought a very tidy Portuguese 5001 7 day on SC around two years ago - it was on sale for some time, bumped/reduced and was great value.
The black dial makes a very smart 'work' watch, and is easily identified as a quality piece by folks who know a little about watches.
I still have it, and still love it,
