This is a Grand Prix Orient, a high-end model from the 1960s that incorporated all of Orient's technology at the time. It now has high vintage value, and the design is a masterpiece in the Calatrava style. The daily rate is unknown as it has not been overhauled, but it is running. Please refrain from purchasing if you are looking for perfection, as this is a vintage item. The case diameter is 35mm, and the wrist size is approximately 15.6cm to 19.3cm. Thank you. #14KGF Gold Filled #Patek Philippe
