Girard Perregaux Foudrayante Ref. 90200

Titanium S.F. Foudroyante with both titanium bracelet and navy sharkskin strap. Beautiful, large box and papers included. I bought the watch new. This watch is in great condition and keeps very accurate time. The lightning seconds hand and the chrono function/buttons work flawlessly. HOWEVER, the button on the crown which activates the rattrapante feature currently does not work therefore you cannot track two simultaneous times. This is a new development and It seems as though the button spring (if there is one) may be broken. Before sending back to GP for repair, I thought I'd try selling as is for a lesser price. Make offer.
