Caliber 177

Manual Winding Movement

Description

Manual Winding Movement.
The caliber 177 is among the thinnest mechanical movements ever made.
Its construction is decidedly ingenious.
With a height of merely 1.77 millimeters, this movement is predestined for Patek Philippe's most elegant watches.
A skeletonized version of the movement is available as well (177 SQU).
To craft it profoundly challenges the artistry and skill of our watchmakers, because all piercework and beveling is done entirely by hand.
