Kindly let me know the difference between Torque hand working and Power Reserve hand working. Let me know the purpose. Link above was very useful. Basically I want to know the difference between Torque Hand Purpose and Power Reserve Hand Purpose being there in the watch. I mean why they exist there?
What is left side hand for? Main Dial is for time(minutes and hours). Right side sub-dial is for Torque. Left Side sub-dial is not possible to read in this image above.
On the website there is a link already mentioning the jewelers and watch companies providing service to Girard-Perregaux. www.girard-perregaux.com/agents/agents_step3_en.aspx?id=US&state=5
