With fitted Cartier presentation box.
The dial of this watch features the notation Bte. S. G. D. G., which stands for "Brevet Sans Garantie du Gouvernement", a French legal remark that signifies the government does not guarantee the functioning of the patented device. Such legal notations (similar examples are "patented" and "patent pending") are sometimes found on movements, dials or cases of vintage pieces.
The watch is furthermore fitted with a gold deployant clasp stamped EJ for Edmond Jaeger, designed by Jaeger in collaboration with Louis Cartier and patented in 1910.
