The Graduate Chronograph is in 904L steel which stands out for its high chromium content. Although it is particularly difficult to machine, this metal has superior corrosion resistance and exceptional brightness after polishing and even after satin finishing along the case and strap.
Girard-Perregaux has equipped the emblematic case with its self-winding chronograph movement GP03300-0135, two counters and small seconds as well as a date. In addition to guaranteeing an impeccably precise timing, it stands out for its convenient power reserve and the particularly fluid activation of its buttons.
