The Rolex Submariner might be the most recognizable watch in the world, and when crafted in two-tone steel and yellow gold like this ref. 116613, the Submariner becomes even more so an icon of serious luxury. We love the six-digit Submariners from this era for the refined case and bracelets, the ceramic bezel insert, the svelte 13mm thickness, and the venerable 3135 automatic winding movement with date and 48-hour power reserve.
