The Rolex Submariner Date 116613lb-0005 with 'sunburst' dial was introduced at BaselWorld 2013. It was an update to the original 2009 Submariner 116613lb-0005, which featured a sunbrust blue dial.
Movement
This model is equipped with calibre 3135, a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 3135 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. It is fitted with a Parachrom hairspring, offering greater resistance to shocks and to temperature variations. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
