CERTINA DS-3 AUTOMATIC, VINTAGE 60s

Certina DS-3 Automatic: Submarine Horology Legend

Origins and Historical Context
The Certina DS-3 Automatic emerged in the mid-1970s as an evolution of the DS-2 series, consolidating the legacy of the Double Security (DS) technology developed by Certina in 1959. This model was born in an era of underwater exploration and high-risk military operations, where instrument reliability was crucial. Its design responded to the demand for professional diving watches capable of withstanding extreme depths and hostile conditions, positioning itself as a tool for military forces and technical divers.

Technical Innovation: The Double Security System
The DS-3 inherited and improved the DS concept, which integrated multiple layers of protection:

• Floating movement suspension: A ring of elastic rubber cushioned impacts, allowing the caliber to move inside the case without damage.

• Reinforced sealing: O-rings in crown, crystal, and case back ensured water resistance up to 1,000 meters (100 bar), a milestone for the time.

• Extra-thick plexiglass crystal: Resistant to pressure deformations, with a locking bezel to prevent accidental rotations.

These features distinguished it from competitors like the Rolex Submariner or Omega Seamaster, offering comparable robustness at more accessible prices.
