Factors affecting accuracy

Mechanical watches have been a symbol of precision and craftsmanship for centuries. However, various factors can affect their accuracy over time. In this blog section, we will explore some of the key factors that can impact the timekeeping ability of mechanical watches, and how to address them.

1. Temperature Changes

Temperature changes can significantly affect the accuracy of mechanical watches. The expansion and contraction of the materials due to temperature fluctuations can influence the movement’s precision. Extreme hot or cold temperatures can cause parts to expand or contract unevenly, leading to variations in timekeeping. Here’s how temperature affects watches:

  • Hot temperatures: High temperatures can make lubricants in the watch movement thin and less effective, leading to increased friction and potential accuracy issues.
  • Cold temperatures: Cold temperatures can cause the lubricants to thicken, which might hinder the smooth operation of the movement and affect its accuracy.

To mitigate the impact of temperature changes, watch manufacturers often design watches to operate within specific temperature ranges. Some high-end timepieces can withstand extreme temperatures better than others due to improved materials and thermal compensators.

2. Magnetic Fields

Magnetic fields are another significant factor that can affect the accuracy of mechanical watches. Modern life exposes us to various magnetic sources, such as smartphones, magnetic clasps, speakers, and even airport security scanners. When a watch’s movement is exposed to a strong magnetic field, the delicate balance of the hairspring can be disrupted, affecting its ability to oscillate at a consistent rate.

To combat this issue, watchmakers have developed antimagnetic technologies. Several brands now incorporate materials like silicon or certain alloys in the movement to increase resistance to magnetic fields. These antimagnetic watches can withstand magnetic forces up to several thousand Gauss without affecting accuracy.

3. Regular Maintenance

Like any other intricate mechanism, regular maintenance is crucial for maintaining the accuracy of mechanical watches. Here’s how regular servicing and maintenance can help keep watches accurate:

  • Cleaning and lubrication: Over time, the lubricants used in the movement can break down or dry out, leading to increased friction. Regular maintenance involves cleaning and lubricating the watch to ensure smooth operation.
  • Adjustments and calibration: The intricate balance wheel and hairspring mechanism within a watch can experience slight shifts or disturbances with age. During servicing, adjustments and calibration are performed to ensure the watch keeps accurate time.
  • Inspection and part replacement: Wear and tear can occur in the movement or other components of the watch. Regular maintenance allows for the inspection and replacement of worn or damaged parts, preventing potential accuracy issues.

Evaluating the precision and reliability of Hamilton timepieces

In conclusion, Hamilton watches are generally known for their accuracy, thanks to their reliable Swiss movements and commitment to precision. However, it’s important to note that individual experiences may vary based on factors like usage, maintenance, and external conditions. To ensure optimal accuracy, we recommend regular servicing by authorized professionals and proper care of your Hamilton timepiece. By doing so, you can enjoy the remarkable accuracy and longevity that these watches are renowned for.
