      EARTH MADE™

      Earth Made™ is a registered service mark of Thümm & Co. It represents our effort to source materials from all over the world in order to produce a high-quality product for an affordable price. We are open about where the materials we use in product development come from because we want our customers to have full transparency of the global nature of our production supply chain.

      In order to develop a product of superior quality and affordability, we must rely on sourcing materials from countries that have sophisticated manufacturing processes and have earned top-notch assembly status. However, we do not solely rely on one country in order to produce our watches—we expand our supply chain based on our design and do not consolidate production in order to stretch our margins.

      The Earth Made™ promise is to never conceal the origin of the materials used in producing your watch. Furthermore, we will never take the easy way out when it comes to material sourcing and promise to always explore all possible manufacturing processes in order to ultimately give you the best value.  

      Thümm & Co. watches are designed in the USA and we have manufacturing partners in the USA, China, and Japan. The design principles of our watches are based on simplicity, functionality, and durability. The elements most representative of our design approach and craftsmanship are the sterling silver bezel and fluoroelastomer/genuine leather straps.

      The sterling silver bezel of the R1 Alpha and R1 Gamma models are made with 96% silver that is hypoallergenic and nickel free. Our USA-based refinery adds a 4% formula of other metals to create additional strength and to slow the natural tarnishing process of the silver. By using a precious metal like silver on the exterior of the watch, we have created a truly engineered fashion watch that, if cared for nicely, can last you a lifetime.The 18mm straps on Thümm & Co. watches are made of a combination of rubber and genuine leather. The lining and strap sidewalls are molded from fluoroelastomer (a polymer) rubber. This provides a sweat-resistant barrier to the entire top station of leather, which is sturdily stitched on all sides. The all-stainless-steel buckle is designed with a 360° shape that will tuck the strap in along with the moveable keeper. The result of this unique engineering provides a supple, long-lasting strap.
