Sternglas appoints Maurizio Koch as COO and drives international growth

Hamburg-based watch brand Sternglas is expanding its management team: Maurizio Koch (pictured left) takes over the position of Chief Operating Officer (COO) and will play a central role in the further scaling of the company and in international growth.

„Maurizio brings exactly the operational strength and international experience that we need for our continued growth,“ says Sternglas founder Dustin Fontaine.

Scaling expert for the next growth phase

Koch was most recently the managing director of the online shop Limberry, which specializes in premium traditional clothing. Over more than six years, he developed the company, expanded the team and brand, and established a high-performance infrastructure in digital commerce. He has over ten years of experience in e-commerce, data infrastructure, shop development, and performance marketing.

According to its own statements, Sternglas is in a dynamic growth phase. In 2025, the brand achieved strong international growth, particularly in the USA. The US market now accounts for around 50 percent of total sales and is expected to expand further in 2026 – despite challenges posed by rising US tariffs.

„Sternglas has enormous international potential. I look forward to working with the team to shape the next growth phase in a structured and sustainable way,“ says Koch.

The expansion of the management team is also expected to benefit brick-and-mortar retail partners. "I am delighted that with Maurizio we are further professionalizing our operational and digital processes," says Dirk Proksch, Director of Retail at Sternglas. "This will enable us to offer our jewelers even faster, more reliable, and better service in the future."„
