Rolex SD43
The Rolex Sea-Dweller SD43, or simply the SD43, represents a significant milestone in the evolution of Rolex’s iconic dive watch. The “SD43” designation itself holds meaning, revealing the watch’s key characteristics. “SD” stands for “Sea-Dweller,” highlighting its lineage as a deep-sea diving watch, while “43” indicates the watch’s impressive 43mm case diameter.
The Rolex Sea-Dweller: A Legacy of Deep-Sea Exploration
The Rolex Sea-Dweller has a rich history, dating back to 1967. Its creation was driven by the demands of professional divers, particularly those working in saturation diving environments. The original Sea-Dweller was designed to withstand depths of 610 meters (2,000 feet), a significant improvement over the 100-meter (330-foot) depth rating of the Submariner.
The Sea-Dweller has undergone several iterations over the years, each incorporating advancements in technology and design. Key milestones include:
- 1967: The first Sea-Dweller, with a 2000-foot depth rating, was introduced.
- 1979: The Sea-Dweller 1665, featuring a helium escape valve, was released to prevent damage to the watch during deep dives.
- 1997: The Sea-Dweller 16600, with a larger case and a 3,900-foot depth rating, was introduced.
- 2008: The Sea-Dweller Deepsea, with a 12,800-foot depth rating and a massive 44mm case, was released.
- 2017: The Sea-Dweller 126600, with a 43mm case, a 1,220-foot depth rating, and a new movement, was introduced.
The SD43: Distinctive Features
The SD43 stands out from other Sea-Dweller models with its distinct design elements. Its 43mm case, crafted from 904L stainless steel, provides a substantial presence on the wrist.
