High-Tech Manufactory Teno
Traditional crafts skill: the diamonds and gemstones are set by hand in a precision setting prepared using CNC technology

All design watches and jewelry at TeNo start their trip in Germany in the historical production site of Pforzheim. They draw on crafts skills, modern technology, visionary ideas and not least the people behind the work. Each item of jewelry each accessory and each watch is manufactured with the greatest possible care and satisfies the highest of all quality standards.

Each individual TeNo ring is polished by hand after series production in order to produce a high-quality surface

The surface of the TeNo jewelry which is mainly fashioned of stainless steel, requires the highest standards of material, The additional requirement of accurately setting or bonding other materials such as gold, diamonds, gemstones, mother of pearl, wood, Indian rubber, ceramics and pearls demands the use of high-tech machines, for example the five-axle CNC machines for lathing and cutting the individual elements or the laser measurement and welding equipment.

Whether it is high-tech ceramics, gold inlay or quite simple and purist – very different methods of surface refinement ensure that each individual item of TeNo jewelry has its own precious luster

From the development to the product. Before the machines are put to use, the designs for the watches and jewelry are drafted using 3D computer images. The programs for series production on the CNC machines are not written until the silver sizing models, the so-called hand specimens, have been altered for as long as it takes to make them right. The TeNo jewelry is not cast; instead all individual components and elements are lathed or cut from solid stainless steel tubing using precision setting machines.

The finished blanks are processed further in various methods – for example with precision pavée settings, performed on CNC-controlled machines. Each individual setting is cut into the stainless steel jewelry to be absolutely and entirely precise. After this, the exactly calibrated diamonds, sapphires and other gemstones are set one after the other by hand.

The pave settings for each individual item of jewelry are cut for the diamonds, calibrated using laser technology

In the stainless steel-gold jewelry collection, a characteristic feature of TeNo products, the solid gold plates are driven by hand into the grooves cut to accommodate them. They are tightly connected with the stainless steel before an elaborate process of grinding. Manual polishing and a very special grinding technique produce a precious, matt luster in the TeNo creations.

The 18 karat gold elements are driven into the jewelry blanks by hand before they are subjected to an additional, elaborate grinding process.
