James F. Cahill was a well-known American diver who assisted multiple state and local police departments, as well as the U.S. Navy, Coast Guard and Air Force in early underwater investigations and rescue missions. As a diving pioneer, he was the first to dive in the waters of New England. Spinnaker wanted to honor him with the Cahill line of watches. This model has a unidirectional rotating bezel and Superluminova on its hands, dial and bezel to improve visibility in low light conditions.
The brand logo on the dial may vary from the one shown in the photos due to Spinnaker.
