About The Permanent Collection
Our Permanent Collection features new, premium watch parts manufactured and designed by Secondhand Mods. Thanks to the success of our “used” parts program, we can offset the typically high costs for new watch parts and provide modders with high-quality parts at significantly lower prices.
