Hi Graham
It's Stewart here from Heuerville. I'm glad you posted this over here.
Like I said to you in our previous correspondence, I was concerned about the dating you put on buying this watch. However, you seem very sure that it was mid 70's.. but I really can't see this tallying up with when these were produced. Even the very earliest known Monnin Heuer divers had a different bezel insert, which adds to the story.

I don't wish to cause any controversy, but the dial quality/detail does look a little 'off' to me. Anyone else have any views on the quality?? My Monnin had high quality super sharp and crisp dial printing???
