Restore the automatic winding efficiency of your premium timepiece with our Gen-Spec Oscillating Weight Rotor Screw. Engineered specifically for professional watchsmiths and advanced modders, this essential axle screw is designed to securely mount the oscillating weight (rotor) to the automatic bridge of iconic calibers including the 3135, 3035, 1570, 2235, and 2135 architectures.

Machined from premium hardened stainless steel to exact genuine specifications, this rotor screw ensures frictionless rotation and long-term durability. It is the perfect solution for replacing worn, stripped, or broken axle screws—a common issue during routine maintenance or custom movement assembly.

Key Features & Specifications:

  • Part Type: Oscillating Weight Axle / Rotor Screw

  • Material: Hardened Stainless Steel (Provides extreme resistance to wear and shearing forces)

  • Compatibility: Precision engineered for Swiss and premium aftermarket clone automatic calibers (e.g., VR3135, VS3135, 3035, 1570, 2235, 2135)

  • Machining: Gen-spec thread pitch and head dimensions to ensure exact clearance under the case back

  • Condition: 100% Brand New, ready for professional installation

Why Choose Our Gen-Spec Rotor Screws?

  • Professional Grade: A stripped rotor screw can lead to catastrophic movement failure. Our screws are precision-milled and hardened to withstand the high torque required during assembly and the constant kinetic stress of daily wear.

  • Restoration Essential: Whether you are servicing a vintage 1570 or upgrading a modern 3135 clone movement, these dimensional 1:1 replacements ensure your automatic winding module operates smoothly and silently.

  • Flawless Fitment: Provides the exact necessary seating depth to eliminate rotor wobble, preventing the oscillating weight from scraping against the movement bridges or case back.

Note: Please carefully select your exact movement caliber from the dropdown menu before adding to cart, as thread pitches and axle lengths vary significantly between models. Professional installation using appropriate watchmaker screwdrivers is highly recommended.
