You know, I think that's the actual watch that got me interested in the GMT-Master - I must have been 10 or so and can remember that episode of Magnum (one of my favourites - Hawaii, Ferrari, helicopter, crimefighting....not the Dobermanns though ) - his father's wasn't it, died in Korea/Vietnam and Magnum had been given it at his funeral. Great episode pretty much all about the watch - must see about getting hold of that.
And look, no Jubilee in sight - just the purists' Oyster!
