Cosmograph Daytona.

1961 release. The only chronograph model in the watch that Rolex produces. It was initially developed for the American Apollo program. In the end they were defeated. But it does not change that it is a popular model.
Its origin is thought to be the circuit Daytona International Speedway, but it is not clear.

その名の由来は、サーキットであるデイトナ・インターナショナル・スピードウェイであると思われているが明らかではない。
