Kieninger Clocks satisfy the highest demands and captivate with their high level of elegance, craftsmanship and reliability. State of the art technology combined with selected woods, the finest materials and the experience of 90 years in crafting clocks and clock movements provide this guarantee.
Kieninger is the oldest existing manufacturer of mechanical movements for grandfather clocks, wall and mantel clocks in the world. Kieninger movements excel with a high level of design and manufacturing quality. Numerous innovations and patents (16-rod chimes; second indication for pendulum lengths under 116 cm; automatic beat adjustment, nighttime shut-off systems for 1/2-hour and 1/4-hour movements; automatic chime sequencing; various manufacturing processes and components) are the measure for design quality.
Manufacturing quality shows in every movement: All movement plates are made of a special brass alloy which is hard and has a tensile strength [Rm] of 520 N/mm2. The holes for the journals are reamed and smoothed after lacquering and then receive an oil sink.
Pinions are made of high-quality steel or stainless steel. Fast turning pinions are hardened. All journals are roller burnished in a special process. Some movements feature bronze-bushings and/or jewels in critical positions. The gears are made of a very tough and hard brass alloy with a tensile strength of 610 N/mm2.
A high level of corrosion protection for all components is assured. Brass components are pickled and receive a coat of clear lacquer. Steel components are made from stainless steel or receive a galvanic nickel coating. Each movement has a laser engraved serial number.
