humism Rhizome 42 mm Automatic Steel Sapphire White Black Leather Unisex Watch,

The Japanese NH35A that powers our watch is renowned for its durability and reliability. As we turn time into art, through the automatic clock, you transform movement into time. This relationship is symbolized in our custom rotor design, shown through the open caseback. Sapphire crystal is incredibly scratch resistant, with a score of '9' on the Mohs hardness scale, just one point behind the diamonds. We use sapphire crystal for both the top and bottom glass, with an additional anti-reflective coating applied to the top glass The case is made from brushed 316L surgical steel, a step above the most common and less durable 304L steel. To ensure accuracy and durability, our discs are incredibly thin and lightweight. Products from years of research, these discs are made with proprietary Japanese technology. Our leather is vegetable tanned, a natural leather processing method that takes much longer than the most commonly found chemical-based chrome tanning method. All our straps are built with quick release pins, allowing you to change style easily.
