 The Hermle 340-020 clock movement has earned its place as one of the most recognized and widely used clock movements in the world. Known for its reliability, precision, and adaptability, this movement has been a cornerstone in the clock making industry for decades. Let’s delve into its history, explore its features, and examine its global reach. A Brief History of Hermle Clock Movements: Franz Hermle established in 1922 in Gosheim, Germany, quickly became a leading manufacturer of mechanical clock movements. The company’s commitment to innovation and quality made it a dominant player in the clock making industry. The 340-020 movement was first introduced in the mid-20th century as part of Hermle’s efforts to modernize traditional clock making. Designed to be both versatile and durable, it became a popular choice for mantel clocks, wall clocks, and other timepieces. Its robust design and reliable timekeeping quickly set it apart, making it a preferred choice for clock makers and enthusiasts worldwide. Key Features of the Hermle 340-020 The Hermle 340-020 movement is an 8-day spring-driven movement, featuring:
Why the 340-020 The enduring appeal of the Hermle 340-020 lies in its perfect balance of traditional craftsmanship and modern functionality. It’s a movement that embodies the best of Hermle’s legacy while meeting the needs of contemporary clock enthusiasts. Whether you’re a seasoned clock maker or a collector, the Hermle 340-020 movement offers unmatched reliability and a timeless connection to the art of horology. Its history and widespread use underscore its significance as a true classic in the world of clocks. Care and Maintenance: Although, the Hermle 340-020 is a workhorse of a movement, reliable and precise, like all mechanical machines, they do require maintenance and service on a regular basis. The Hermle 340-020 is manufactured in Germany and shipped all over the world. Although they are oiled and tested prior to shipping, during the shipping is where the problems start. A clock movement has what is called an oil bushing. this is where a small amount of clock oil sits to oil a moving clock movement. All is fine, as long as the clock is running and the clock oil is being drawn up and oiling the pivot. Once a clock movement sits for awhile, the oil will pool up at the bottom of the bushing and eventually run out, especially if the movement is not sitting upright in its case. When a clock manufacturer like the Howard Miller Clock Company receives the 340-020, they will re-oil the movement prior to installing it into the clock case, then ship it to a retail store or directly to someone who has purchased it on-line. However, if a person was to purchase a Hermle 340-020 directly from a store or the internet, they will receive it dry, with little, if any clock oil in the bushings. Not knowing this, the receiver of the Hermle 340-020 will install the movement, start it up and let it run, thinking all is good, only to have it worn out within a few years. These movements, like all mechanical clock movements require servicing and cleaning. Learning to service, clean and oil a clock movement yourself is not all that difficult. At Horace Whitlock Oil Company, we provide a free downloadable file that will show you step by step how to clean and re-oil a clock movement like the Herle 340-020. With all this said, if you are changing out an old Hermle 340-020 with a newer one, we highly suggest you download this file and perform all the necessary steps prior to installing your new Hermle 340-020 movement.

If you have a Black Forest cuckoo clock, you might be wondering if it needs to be oiled and how often to keep up with this maintenance.  How Often Should I Oil My Cuckoo Clock?
As a general rule, cuckoo clocks should be oiled every two to three years; average wall clocks need to be lubricated every three to five years. Oiling keeps everything running smoothly, so don’t skip it. We recommend posting a sticky note on the back of your clock, listing the dates of any maintenance. Also, set a calendar reminder on your phone or desktop, so you don’t forget when it’s time to oil your cuckoo clock. Why Do I Need to Oil My Cuckoo Clock? Anything with gears and metal moving parts will need to be oiled, just like parts of your car. You need to keep up with the oiling maintenance on any mechanical clock because if the movements get dry, it will cause severe damage to the clock. Not to mention the clock will not work correctly, and metal will be grinding against metal. Inside the clock’s delicate movement box are carefully placed “oil sinks,” or oil wells, next to the plates and pivot holes where the axles connect. These oil sinks lubricate the clock in all the right places. What Kind of Oil Should I Use on My Cuckoo Clock? The best oil to use for your cuckoo clock is one that is synthetic and high quality. Horace Whitlock's Clock Oil is specifically designed for all mechanical clocks. Since you don’t need to oil your clock often, it’s best to buy dedicated oil for clocks instead of using just any old oil. The oil designed for clocks should stay put — as opposed to the oil used for things like sewing machines, which is intended to spread. So you may think you can use whatever oil you already have, but we suggest buying the correct oil — and never use WD40 on your cuckoo clock or any clock. The WD in WD40 stands for water displacement. When oils come in contact with WD40 the oil is displaces and removed from its location, leaving behind a thicker motor oil type lubricant that is not intended for precision equipment such as a Cuckoo clock or any other clock for that matter. You can find the right oil easily at many online retailers or visit your local clock store. A popular oil brand that comes highly recommended is Liberty. The clock oil has a long needle at the tip that can maneuver into hard to reach places and place the oil in the right spots. Where and How Do I Oil the Cuckoo Clock? Cleaning and oiling a Cuckoo clock is not that difficult. Most clock shops charge quite a bit to service a cuckoo clock. On the Horace Whitlocks home page, you will find a free downloadable PDF guide that will walk you through this process. We suggest you down load this file and read it carefully. Although its not directly for a cuckoo clock, it is a generic file for cleaning and re-oiling any type of mechanical clock. Once your comfortable with the information, we suggest you purchase a good quality oil and get started. Horace Whitlock's Clock cleaning and oiling kit is the perfect kit that includes everything you will need to clean, re-oil and service your cuckoo clock. Although the kits instructions suggest you remove the cuckoo clocks movement, this is not necessary, you can do a good cleaning and re-oiling by opening the back to access the movement box and specifically the pivot points. Wipe around them gently with a soft cloth provided to remove any excess dirt and old oil deposits. Using a pivot cleaning stick also provided, you’ll clean the area more closely. Do not use Q-tips for this. Place a drop or two of oil in the oil sink, but do not overfill — and be careful not to disturb other working parts of the clock. We put this cleaning and re-oiling kit together with the instructions with the hobbyist in mind. Although we do sell these kits to both the hobbyist as well as professional clock repair shops.

Your clock is more than just a timepiece; it’s a living piece of history, a functional work of art, and sometimes even a cherished heirloom. To keep it ticking smoothly, regular maintenance—including proper lubrication—is essential. Here are five telltale signs that your clock may need oiling:
1. Erratic Timekeeping: Does your clock lose or gain time inconsistently? Erratic timekeeping is one of the most common signs that the internal mechanisms are not functioning efficiently. Friction between unlubricated parts can slow the movement, making it difficult for the clock to maintain accurate time. What to check:
A clock’s rhythm is music to a horologist’s ears. If you notice the ticking sounds uneven, muffled, or louder than usual, it could mean the gears and pivots are struggling to move due to a lack of lubrication. What to listen for:
Even in the most pristine environments, dust can accumulate on your clock’s moving parts. Over time, this build-up can mix with old oil, turning into a sticky paste that hinders the mechanism’s smooth operation. What to inspect:
If your clock has a pendulum, its swing should be steady and consistent. A reduced or uneven pendulum motion often indicates increased friction in the clock’s movement, signaling the need for cleaning and oiling. What to observe:
Even if your clock seems to be running fine, regular oiling every three to five years is crucial to prevent wear and tear. Neglecting this maintenance can lead to costly repairs down the line. What to verify:
Why Proper Oiling Matters Using the right clock oil, like Horace Whitlock’s Clock Oil, ensures optimal performance and longevity for your timepiece.
