The SUS316 stainless steel blank is processed in more than 30 processes and finally polished, polished and filled by hand by watchmakers.  Round sand on the front, light on the inside and outside rings, and sandblasting with teeth, you can feel the Swiss design team's meticulous craftsmanship of this watch from all angles, and each watch is a unique work of art.  The raised rim design of the powerful "KAVVO Mountain Ridge" provides full impact protection for the lenses and the surface, allowing you to use it in harsh environments. 

The SUS316 stainless steel is precision machined, and the 24 batch teeth of the "KAVVO Mountain Ridge" design make the magic crown smoother.
