I do love photoshop but this photo is unaltered. Actually I think that the photo doesnt do justice to the size differential.
The photo only shows width (area) of the watch - but in three dimensions it is about volume. Very roughly I'd say the ploprof face is double the area of the triple date. But it is three times as thick, so we are talking six times the volume...

Of course there are bigger watches out there these days (bell&ross br01 is 46mm, to name one) but in 1970s it really must have looked bizarre.

I have to sign off with the words of the great chuck maddox - who was not a big ploprof fan - he said something like (I can't remember exactly) "wearing a ploprof to go to the shops is like bringing an aqualung to a paddling pool" .....I love the comment, even if I admit I do sometimes wear it to go to the shops...
