Kieninger

What Kieninger does

Kieninger, legally operating as KUMA GmbH, is a German precision mechanical clock manufacturer founded in 1912 in the Black Forest and headquartered in Aldingen between the Black Forest and the Swabian Alb. The company is the oldest existing manufacturer of mechanical movements for grandfather, wall, and table clocks in the world and the oldest existing German manufacturer of large mechanical watches. It employs approximately 50 highly qualified master watchmakers in a 6,000 square meter manufacturing facility built in 1991.

The company's core offering is its in-house manufactured mechanical clock movements, which power a portfolio of floor clocks (Standuhren), wall clocks (Wanduhren), and table clocks (Tischuhren), plus a Special Editions line of limited-run timepieces. Its technology base includes six granted patents covering automatic night shut-offs, automatic escapements, correct seconds display, automatic melody change mechanisms, and the Kieniramic® Graham armature trademark, plus proprietary processes like roller burnishing and a torsion-control module. Premium materials such as chrome-plated brass, gold-plated components, ceramic pallets, ruby bearings, and ball bearings are used across the movement line, and products feature a 7-day power reserve.

Kieninger operates a direct-to-consumer go-to-market, selling primarily through its branded e-commerce storefront kieninger-uhrenshop.de with personalized consultation for affluent individual collectors of luxury mechanical timepieces. Pricing is quote-based and not publicly disclosed. Since early 2021, the company has been owned by KUMA GmbH, founded by four shareholders (Leopold Grimm, Gerhard Schneider, Robert Eby, and Dr. CK Ip) who took over from the prior American owner, the Howard Miller Group. Revenue is not publicly disclosed and there are no external funding rounds.
