The Instrumento Grande Open Date is the latest watch from the Geneva based jewelers and watchmakers De Grisogono. The watch is based on previous designs by De Grisogono but exposes the two dials which operate the date mechanism giving the watch a unique look. The watch is available in either rose gold or De Grisogono’s signature Browny Brown gold with grained calfskin or alligator straps and it uses the GD 15-89 automatic movement.
