PP CH 27-70
Calibre CH 27-70 is a manual winding chronograph movement by Patek Philippe.
The CH 27-70 is based on the Lemania 2310. It was the last not fully in-house produced movement by Patek.
It was used in the Chronograph 5070 model.
It was also base for a perpetual calendar complication. Later also a rattrapante function was added.
