Rolex Oyster 4125 Description

Known as the “King-of-Wings,” this manually-wound WWII-era model is historically significant as part of Rolex’s “Air” series honoring RAF pilots. With a large 35mm case and legible dial, it was designed as a robust instrument for aviators. Its importance lies in Rolex’s targeted marketing towards military aviation, cementing the brand’s reputation for creating professional “tool” watches and marking a key step in their legacy of purpose-built timepieces.
