The Rolex Submariner is arguably the most iconic wristwatch ever produced by any manufacturer. Initially released in 1953, the Submariner was the world’s “go to” professional diver’s wristwatch, and today it has become “the” go to watch. Earliest examples of the Submariner featured a time only function with no date. However, in the late 1960s Rolex released their first ever Submariner reference with a date function via the ref. 1680.
