Bamford Watch Department, the company famous for its Rolex customizations, will be revisiting two classics: the Submariner and Military Submariner, perhaps the two most famous dive watches in the world and some of the most coveted watches for collectors.

Taking its cues from the masterful Submariner 6538 Non Date—made famous by Sean Connery’s James Bond—is the Bamford Heritage Submariner. With a military-grade titanium coating, black bezel, gilt hands with ivory luminous tracking and a streamlined look resulting from the removal of the crown guards, the Bamford Heritage Submariner has a contemporary look but is every bit the timeless collector’s item. The red triangle makes for an elegant yet bold statement.

The Bamford Milsub is a similar take on the Military Submariner 5517—the standard issue dive watch of the Ministry of Defense from 1971 to 1979. With a larger bezel, fixed bars and 60 minute hash marks, the Military Submariner was, as the name would suggest, built to the slightly more exacting specifications of military personnel. The Bamford edition reintroduces these, as well as the immensely popular sword hands of the original. It also includes a circled letter replacing the Tritium logo of the original, which can be customized by the purchaser.

Both watches are set to sell for $19,375.
