The hallmarks stamped on the sides of the lugs remain exceptionally deep and original. Most importantly, the original dial remains in exceptional condition. The present lot is further accompanied by its Certificate of Origin dated 1991, original fitted presentation box, sapphire crystal and solid gold casebacks, 3970 promotion leaflet, and all related booklets.
