Sea-Dweller (Reference 126600). A stainless steel automatic wristwatch with date and bracelet. Circa 2017

The Rolex Sea‑Dweller Reference 126600, widely known as the SD43, is the modern deep‑sea professional diver introduced in 2017 to mark the 50th anniversary of the Sea‑Dweller line. Its 43 mm Oystersteel case established a new, more contemporary scale for the model, while retaining the helium escape valve and saturation‑diving pedigree that define the Sea‑Dweller family. The dial features the celebrated red “Sea‑Dweller” script, a deliberate vintage callback to the earliest references of the late 1960s. Powered by the Calibre 3235, the 126600 delivers extended autonomy, enhanced chronometric performance, and the robustness expected of Rolex’s professional‑grade engineering. As the anniversary reference, the SD43 occupies a distinctive position in the modern Sea‑Dweller lineage, a blend of heritage cues and next generation technical capability.
