Swiss. 40mm. Circa 1970. There was a time when the Submariner was most commonly worn for its intended purpose of sport and professional scuba diving. I will always maintain that "purpose built" watches are the most enduring in design and style. If you question the iconic legacy of the Submariner, call your local Rolex authorized dealer and ask how many they have in stock. Box & original warranty card are included. Offered subject to reserve. CODE-WAT
