ETA SA SL4609

The SL4609 is an automatic chronograph movement manufactured in China, based on the ETA 7750 framework with a cam-style chronograph system. It operates at 28,800 vph with a 45-hour power reserve and features 33 jewels with Incabloc shock protection. Unlike the standard 7750, the subdial layout places the small seconds at 12:00 and the 30-minute counter at 9:00, while maintaining the tri-compax layout with a date window at 3:00. The movement currently appears in the Sugess Titanium Chronograph S464.
