The journey of a watchmaker is one that is lifelong with no real end destination. While there is no doubt that technique and skill will develop into expertise over time, there is always some area to develop or a new skill to hone. Although the key elements of watchmaking have stayed the same for centuries, the traditions of watchmaking are constantly evolving thanks to new technology. Regardless of whether you are new to the game or have been working on timepieces for years, there will still be something to learn or some room for improvement. When you are just dipping your toes into the world of watchmaking, you are guaranteed to make mistakes; it is all part of the learning process. However, novices are not the only ones who make mistakes, and some experienced watchmakers can still habitually make mistakes. No matter where you are on the watchmaking road, it may interest you to know the most common watchmaking tool mistakes and how to avoid them.

1) Overtightening Screws and Stripping Threads: Proper Torque and Screwdriver Techniques

One of the most common mistakes in watchmaking is overtightening screws which can strip threads, damage delicate components and make future disassembly difficult. Watch screws are small and made from soft metals, requiring precise torque application rather than brute force. To prevent stripping threads, always select a screwdriver that matches the width of the screw head exactly. A poorly fitting screwdriver can slip and damage the screw slot, leading to damage that will make it difficult to use again in the future. Apply gentle, controlled pressure and stop tightening as soon as resistance increases, as over-torquing can cause permanent thread damage.

For added control, hold the screwdriver between your thumb and index finger while using your middle finger to stabilize and guide it. If a screw offers resistance when removing, avoid forcing it as this could indicate corrosion or debris in the threads. Instead, apply a small amount of lubrication and gently work the screw loose. Using high-quality and well-maintained screwdrivers with properly sharpened tips also reduces the risk of slipping or stripping. 

2) Opting for Cheap Screwdrivers: Why You Are Wasting Money

Building your toolbox is not cheap, and a considerable amount of money will need to be spent on the equipment you need for your watchmaking tasks. It is important to think of your watchmaking toolkit as an investment, one that, if you spend the money, will reward you with quality, precision, and reliability. Although there are some tools where you can afford to choose the cheaper alternative, cheaper screwdrivers should be avoided if at all possible. For many watchmakers, cheaper tools have proven to be more expensive in the long run, with a need to replace them on a regular basis. They are also known to damage screws and timepieces as they are often not specifically designed for the delicacy of watchmaking. Our recommendation would be to purchase from a reputable watchmaking brand, such as the likes of Bergeon or Horotec.

3) Not Sharpening Screwdrivers: Keep Them Precise

Screwdrivers seem like relatively simple tools that require little maintenance. However, they are one of the most important tools to take care of. It is common for watchmakers to neglect screwdriver maintenance, particularly by beginners, as the importance is underestimated due to a lack of knowledge. When it comes to tool maintenance, screwdrivers are one of the most important to look after, and it is essential to regularly evaluate the condition of your screwdrivers and sharpen them when necessary. 

Dull, blunt, and broken screwdrivers can damage the screw head, which makes it difficult to screw or unscrew at a later date. If the screw head becomes damaged, the screwdriver cannot achieve the appropriate grip to screw correctly. A damaged and blunt screwdriver also increases the risk of slipping, which can damage or scratch the actual watch. It is, therefore, crucial to keep them precisely sharp to ensure that your watchmaking tasks are efficient. 

Sharpening your screwdrivers also secures your investment. We have discussed the importance of purchasing a high-quality screwdriver set but the investment in this is not worthwhile unless a watchmaker takes care of their screwdrivers. Sharpening your screwdrivers will increase their longevity and reliability.

4) Using the Wrong Tweezers for Delicate Parts: Preventing Damage to Balance Wheels and Hairsprings

Tweezers may seem like a relatively basic tool, but nothing will prepare a watchmaker for the true size of the small parts you will be working with and the fragility of a timepiece. Fine motor control is one of the most important skills you will learn in watchmaking, and choosing the correct tweezers can not only support you during skill development it will also prevent damage to delicate watch parts.

5) Improper Cleaning Practices: Ensuring Longevity and Precision

Cleaning is a practice that easily gets neglected in watchmaking but is a crucial part of watch maintenance. It is important to clean the exterior of the timepiece regularly to retain its luster and aesthetic appeal, however, when working with the inner parts of the timepiece, it is also important to clean. A movement’s biggest enemy is dust and debris, so ensuring that watch parts are cleaned before reassembling the watch is critical. The precision and performance of a watch can drastically reduce with failure to clean components correctly. 

6) Lubrication Mishaps: The Importance of Lubricating Correctly

Lubrication is an area of watchmaking that can be neglected due to the intricacy of the task. As a result, many new watchmakers skip the step, choosing to avoid it rather than struggle with it. There is no doubt that lubrication is a tricky process, and even the most experienced processes can over-lubricate. The art of movement lubrication is an extremely important skill to hone in your watchmaking journey. It is important to know that it is possible to make this mistake regardless of your level of watchmaking expertise, so do not shy away from this important step. If you always use the recommended amount of lubrication and the correct type of lube for each watch part, you cannot go too far wrong. Try not to guesstimate; precision is key for lubrication.

7) Inadequate Sealing: Ensuring Water Resistance

Sealing a case correctly is an important step when reassembling any watch, particularly one that has a water resistance level. Failure to seal the case correctly can result in moisture entering the interior of the watch, which compromises the timepiece’s water resistance and can impact the inner workings of the timepiece. It is crucial to always examine any gaskets and seals for wear while also being aware that some are considered to be one-use only and will not seal as effectively again. Replace seals and gaskets where necessary and use the proper tools to close the case securely. A screw-down watch press will offer the most precision in this department, offering more control while replacing the case back without overtightening. 

8) Mishandling the Movement: The No hands Concept

A watch’s movements are so delicate and fragile that even contact with your hands can result in damage. It is important to remove, replace, and move any parts with precision and delicacy to ensure that they do not get damaged and also avoid contact with contaminants. One of the most important rules is to avoid touching the movement and parts with your hands. Oils, dust, and debris can transfer from your skin, resulting in corrosion or poor performance. During your watchmaking tasks, gloves or finger cots are essential, while tweezers are a watchmaker’s best friend.

9) Incorrect Hand Alignment: How to Avoid Malfunction

The watch hands are one of the most essential elements of a timepiece as they are the signifiers of time, and when reassembling a timepiece, it is important to align the hands correctly to avoid malfunction. The hands need to be properly seated, ensuring they do not touch the dial or each other. If contact is made, performance can be reduced, or the watch could stop completely, while if this error is not corrected, it can also damage the hands over time.

10) Excessive First: Go Light and Easy

Applying excessive force is one of the most common errors in watchmaking, a mistake that all levels of watchmakers are guilty of. Excessive force, regardless of the task, can result in irreparable damage, either to the aesthetic of the timepiece or the functionality of the part. From removing watch hands to replacing a case back, patience is a virtue. There is no doubt that certain tasks can be frustrating. However, it is extremely important to reevaluate the situation and your approach rather than risk damage and breakage. With every watchmaking task, go light and easy, taking the time to ensure your precision is correct.

11) Neglecting Testing: Confirming Before Completing

Before you declare that the watch is complete, it is important to test the timepiece. This step is easy to neglect or miss out on, resulting in a watchmaker kicking themselves later when they discover the timepiece is not functioning correctly. It is important to test the watch’s accuracy to ensure it is operating with precision and check the power reserve, if necessary, to ensure its longevity. A further step is to pressure test the watch to ensure its water resistance is retained. Although a pressure tester is an investment, it is worthwhile for your watchmaking tasks, particularly if you are regularly working on timepieces and have multiple watches in your collection. As an alternative solution, a local watchmaker can also pressure test a timepiece for a fee.

12) Attempting too Complicated Tasks: Going Beyond Your Skill Level

Watchmaking is a journey where you will develop skills over time as you progress. Tackling new tasks is an essential step in your learning experience, however, taking on tasks above your skill level without the correct guidance can end in disaster. There are many ways you can learn new watchmaking tasks with courses that can teach you the process in an educational environment. However, if you prefer to be self-taught and explore the art of watchmaking yourself, do not attempt new tasks on a timepiece of value. Watchmakers who practice solo should have some inexpensive timepieces that they can work on to practice new skills and tasks before attempting a complicated task on a valuable watch. If things go wrong and you are working on a watch of value, either financial or sentimental, it can cause irreparable damage. It is advised to seek guidance on challenging tasks and that attempting these tasks on your own is at your own risk.
