Deepsea

The Rolex Deepsea takes the familiar dive-watch formula into thicker-crystal, greater-depth territory, with the Ringlock system built to withstand pressures far beyond recreational diving. Its family spans the 44mm steel models, a yellow-gold version, and the much larger titanium Deepsea Challenge—distinct watches united by engineering you can feel on the wrist.

The original 116660 arrived in 2008 with caliber 3135 and a 3,900-meter depth rating. The D-blue dial followed in 2014, its blue-to-black gradient punctuated by green Deepsea lettering; the black dial remains the quieter alternative. In 2018, 126660 introduced caliber 3235, a broader bracelet, and revised lug proportions. The subsequent 136660 retained that movement while bringing further refinements, including a larger date aperture.

The outer branches are unmistakable. Introduced in 2022, the Deepsea Challenge uses a 50mm RLX titanium case, omits the date, and is rated to 11,000 meters. The 2024 yellow-gold 136668LB instead keeps the 44mm format, pairing a blue dial and blue ceramic bezel with the considerable heft of a gold case and bracelet.
