I've been retired now for nearly ten years.
All my working life was spent as an Engineering designer, a draughtsman to most.
When my drawing were prepared, they had to be 'checked' by, yes you guessed it, by a 'checker'.
Often the checkers would be busy and I had to 'CHECK MY OWN WORK'
Now from experience I can tell you that this is IMHO is impossible, and it never worked for me.
How on earth can anyone give a seal of approval to themselves?
e.g. I've done well today, think I'll give myself a 'D in W' seal......utter rubbish, it's meaningless.
For me internal regulation is......no regulation.
I have lost a lot of faith in Patek over this PP seal business, and all because they (PP) got their knickers in a twist when the Geneva seal was issued to Cartier. Just like some spioled child.
Excuse my rantings, just had to get it off my chest.
D in W
Brin back...
