Hermle Clock History

Hermle Clock History

Nearly one hundred years ago, Franz Hermle began manufacturing and selling mechanical clocks. In 1922, Franz Hermle founded the Franz Hermle Clock Company in Gosheim/Wuerttemberg, Germany. Within ten years the company became known as one of the most modern and efficient manufacturers of clock movements in the clock industry. Franz Hermle and his sons’ dedication weathered the effects of WWII and made Franz Hermle and Sohn, prosper while other companies capitulated.

The founder, Franz Hermle, died in 1953 and left a modern and prosperous operation to his sons Gebhard, Alfred, Hans and Heinrich Hermle. They have continued to build the company into a worldwide leader in the manufacturing of clocks, and mechanical clock movements.

“HERMLE” clocks are produced from one of the most modern clocks making plants in the world. Operating from 2 plants in Gosheim, 1 in Reichenbach, Germany and another 1 in Amherst/Virginia, USA covering about 150,000 square feet and a work force of 500, it has been acclaimed as a center for advance technology and high efficiency. Its production programs range from traditional clocks with mechanical and quartz movements, with or without chime, to high tech radio controlled clocks. Nearly 100% of the parts are made in-house with advance equipment and machinery. Molding, metallizing, lacquering and production of very complicating turn parts needs to be carefully controlled to ensure that every piece of “HERMLE” clock meet up to the highest standards of precision and quality.

Hermle Factories

One of the recent investments in machinery has been in the procurement of precision equipment to finish the pivots on each clock arbor after all the dust preventive plating materials have been removed. These machines placed a polished finished on the pivots and careful checks are made to ensure that rigid quality control standards are maintained. This improvement should extend the lives of “HERMLE” movements considerably. The Company has also invested a considerable amount of capital in improved processes to finish the pivots on the train wheels in the mechanical clocks. All nickel plating is removed from the pivots and then they are polished using these machines. Then careful inspections are made during each step of this operation. The factory is now working on developing additional features for lesser-priced movements and expects to launch these items in the near future. Hermle is the world leader in the manufacturing of mechanical movements, producing more that 1 million units annually and sells to over 130 countries around the world. It’s not surprising that you will find that many of the mechanical clocks in the market are fitted with a “HERMLE” movement.

Applying Modern Technology To Clock Making
Within a few kilometers of where the Danube River begins its journey to meet the waters o f the world. Hermle products begin on their way to almost every country on the globe. Like the Danube, the Hermle factory system has adapted itself to meet the changing nature of the modern marketplace and still maintain a strong forward momentum. The Hermle factories engaged in making both mechanical and electronic clocks are nestled in a picturesque Black Forest valley in southern Germany. The planes are located in the shores of Reichenbach and Gosheim. This valley has always been the home of the Franz Hermle & Sohn Uhrenfabrik and over the last 70 years it has become one of the major business enterprises in the area. The valley has traditionally been the home of several factories engaged in the production of precision machinery and small mechanical components, so there is an abundance of skilled labor available. Even though some of these factories have grown to a considerable size, the valley has never taken on an urban character and still maintains a quiet village atmosphere that is ideally suited for clock making and precision manufacturing. This quiet way of life has not impeded the progress of the factories in the area. Most of them are as modern as one would expect to find in any of the major industrially developed countries of the world. All of them have had to automate their operations to the maximum extent possible so they can remain competitive in their respective markets. Franz Hermle and Sohn is no exception in this regard. They have constructed a factory complex which is one of the most modern and efficient facilities in the world for manufacturing both mechanical and electronic clock movements. Hermle mechanical clocks start their existence in the Reichenbach plant, which produces almost all of the component parts that are found in the wide range of mechanical movements the company manufactures. Several semi-automatic machines that have traditionally been associated with the production of mechanical clock parts have been upgraded with computerized control mechanisms to increase the number and type of functions they can handle. The increased efficiency of these modified machines, as well as the recent investments the company has made in new computerized machinery, has enable Franz Hermle & Sohn to continue to provide their products at very competitive prices all over the world. Almost very operation in the Reichenbach plant has been automated and very few workers are required to produce a sizeable quantity of parts for the Hermle assembly lines and spare parts stocks. These continued innovations have helped to reduce the greatest cost factor in any precision manufacturing operation – the cost of labor. In most cases these changes have not been made at the expense of Hermle employees, as those displaced by automation have been relocated to other production activities in another part of the factory system. One of the most recent investments in machinery has been in the procurement of precision equipment to finish the pivots on each clock arbor after all the rust preventive plating materials have been removed. These machines place a polished finish on the pivots and careful checks are then carried out to ensure that rigid quality control standards are maintained. This improvement should extend the lives of new Hermle movements considerably.Even those operations that still have to be accomplished by hand have been automated to the maximum extent possible. The drums that operate the hammers on chiming movements are still assembled by hand but every effort has been made to make the parts available to the assembler in a fast and efficient manner. Other operations such as the assembly of automatic beat setting services are best accomplished by it but automated machinery that can sense the correct tension on the spring is used so the operation can be carried out quickly and efficiently. The clock plates for mechanical movement are prepared on the lower level of the main Gosheim plant. After being stamped from a roll of sheet brass each plate is brought to a perfectly flat state and the decorative designs are placed on it. Great care is taken in drilling the holes in the plate that will accommodate the wheels and other components. The plate is prepared for finishing and is given a coat of baked lacquer before it is sent on its way to become part of a mechanical clock movement in the assembly facility. The assembly of mechanical movements is accomplished on the upper levels of the main plant building in Gosheim. Wheels are placed between the plates and the movement starts its journey down the assembly line on a conveyor belt. At each station employees add additional parts to the movement and place it back on the conveyor. This process is continued until the movement is completed and moves to the inspection station. All Hermle mechanical movements are test-run for one winding cycle on racks adjacent to the assembly facility. The company devotes a respectable amount of its staff and their time to quality control operations. A considerable investment has been made in computerized equipment to upgrade the quality control efforts of the company. Most of the mechanical movements are prepared for shipping to Hermle customers all over the world once they have completed their test runs. Other movements are transferred to the new Hermle plant in Gosheim located only a few blocks away, where they are installed in cases procured from local suppliers. Most of the clocks assembled in this facility go to Hermle’s European customers and to fill special orders. While Hermle operates a subsidiary plant in Amherst, Virginia, it is not economically feasible to equip most of these facilities with duplicate machinery. Some parts for mechanical clocks that require specialized machinery or complex manufacturing processes are made in the Reichenbach and Gosheim plants and shipped to Amherst. Every part that goes to the U.S. plant is given a 100 percent quality control inspection before it leaves Gosheim. Components for Hermle electronic clocks are produced in the buildings that house the plastic injection machines. These parts undergo several different types of finishing processes before they enter the assembly facility. The basic electronic movement is assembled totally by automated equipment. Different components are then added to the basic movements to produce a wide range of functions and features available to Hermle customers. Even though the basic movement is assembled by an automated process most of the operations required to add the additional features can be accomplished by hand more economically for limited production runs. Hermle electronic 400-day clocks are assembled in the new Gosheim plant by teams of two employees. Each clock is totally assembled by these teams, which is somewhat different than the traditional production line approach used in most factories. The assembly of each electronic clock can be completed quite quickly and efficiently using this method. Several work stations in this facility allow the assembly of different quartz electronic 400-day models at one time. The Franz Hermle & Sohn showroom in the headquarters building reflects the wide range of horological products the company is capable of manufacturing. These range from traditional, weight-driven clocks to new, state-of-the-art, radio-controlled timepieces. The different styles and features, appearing on clocks made to satisfy the tastes of people in different parts of the world, emphasize the extent of the distribution of Franz Hermle & Sohn’s products.

Now in its third generation, Franz Hermle and Sohn employs over 500 people in 4 locations in Germany and an additional manufacturing facility, Hermle Black Forest Clocks, in Amherst, Virginia, USA. We export clocks and clock movements to more than 100 countries worldwide and are dedicated to leading the industry in computerized and automated precision manufactured clock parts and mechanical and quartz movements.
