Of course we won’t miss the opportunity to be present at this year’s INHORGENTA with an impressive booth and our competent sales team. Having already warmed up with our booth at the T-Gold in Vicenza, our team is now fired up to present you amazing product highlights from our TOP brands.

The great number of our trade show appearances each year shows: We keep our finger on the pulse of the industry and continue to value “face-to-face” communication. Of course we appreciate and use the opportunities of digitalization in our daily work to professionalize our processes. But that is precisely why the personal encounters with customers and partners during trade shows are a very special highlight in our calendar. Nothing creates more trust and shows more appreciation than a personal conversation, a friendly smile or a firm handshake. Visit us at booth A2.222 and convince yourself of our quality, competence and service!

At our booth, you will discover a multitude of brand-new innovations to marvel at, in addition to our well-known best-sellers. Special highlights at our booth will be the freshly released SMARTPRO AIR DO for pneumatic engraving and stone setting, our SWISOTECH height adjustable workbenches (fully equipped with air pressure and vacuum), professional WALDMANN workshop lighting, our MAGIC laser and CNC engraving machines, the extensive range of SMARTPRO diamond testing devices, the famous premium watch tools from BERGEON and many more.

We look forward to seeing you in Munich!

It would be a pleasure for us to welcome you on our booth!
