GP is indeed two companies in one.
The haute horology is a totally different department from the mainstream laureato.
In 1988-90, when the GM Francois Besson did a management buy out from DESCO, he brought back the High Horology. When Luigi Macaluso bought GP from Besson, he continued this path.
In fact, there a was a 3rd tier being JDR.
sometimes the tier 1 and tier 2 of GP would come together for a special piece.
For example a laureato case with 3 bridges within.
