The Wolf Group has established itself as a highly automated manufacturer of watch cases, bracelets, and buckles on a global scale. Wolf Suisse is a complete independent and versatile manufacturing hub, catering largely to Swiss clientele, including well-known Swiss watch brands.

Sellita was established in 1950 as an assembly house, procuring ébauches (movements in kit form) from ETA, assembling them, and subsequently distributing these completed movements to watch brands. Today, the company employs around 500 staff at three locations in Chaux-de-Fonds and Jura, Switzerland, and Glashütte, Germany. Sellita has always operated as a B2B enterprise, quietly providing the watch industry with a substantial number of well-tested mechanical movements annually. In recent years, this number has reached as high as 1.2 million; this exceeds Rolex's production and is second only to the Swatch Group/ETA. Sellita has been marketing its own movements for just the past 20 of its 72 years in business, and since 2004, the movements it supplies have been primarily based on historic, expired-patent ETA designs. Now, Sellita is gearing up to introduce a new series of original, high-performance movements to set itself apart from the competition

Headquartered in Austria, this family-owned and operated business was founded in 1765 as a leather workshop and tannery. With over two centuries of innovation in the watch industry, Hirsch's Rembordé construction technique, patented in 1955, which allows for the seamless connection of upper and lining leather, still sets the industry standard today. Hirsch watch straps are attached to more Swiss watches than any other watch strap company. As an OEM manufacturer, Hirsch supplies straps to most Swiss watch brands, including The Swatch Group and Panerai. The majority of Hirsch's product lines are still crafted in Austria, where quality and expertise are passed down from one generation to the next. Hirsch's discerning taste for premium leather hides and quality steel buckles has established them as a top strap solution for the majority of high-end watch brands.
