Frequently Asked Questions
What makes the El Primero 3600 SK different from standard El Primero movements?
The SK designation indicates a skeletonized version where material has been strategically removed from plates and bridges to reveal the movement's inner workings. Despite the material removal, the movement maintains its 5Hz frequency and precision timing capabilities.
How does the 1/10th second chronograph work?
The high 5Hz frequency allows the chronograph seconds hand to make 10 ticks per second, enabling direct reading of 1/10th second intervals on the dial. This eliminates the need for complex additional complications while providing enhanced timing precision.
Is the ZenClasp available on other Zenith models?
Currently the ZenClasp is exclusive to the Chronomaster Sport Skeleton collection, though Zenith may expand this clasp technology to other models in the future based on collector response.
