Please specify whether you would like your watch to be made of Mineral Crystal or Sapphire Crystal when you inquire with us.


Our crystal factory and stainless steel factory operate relatively independently to maintain the professionalism of each team; however, they also collaborate closely with each other. Sapphire is a key component in almost every watch, as well as in various consumer electronics such as mobile phones, smartwatches, wearables, cameras, optical instruments, jewelry, and other industries.
