Whether you’re a watch enthusiast, a collector, or a professional watchmaker, this guide will provide valuable insights into choosing, using, and maintaining this specific size of watch hands.
The Importance of Watch Hands in Timekeeping
Watch hands are more than just decorative elements on a dial; they are the fundamental components responsible for indicating the time. The design, size, and material of the hands are all crucial in determining how effectively the watch performs. With the 1.35/0.85/0.20 mm interior diameter watch hands set, the internal diameter plays a pivotal role in the accuracy and longevity of the timepiece.
The hands need to be precisely aligned with the hour markers on the dial, and any misalignment or incorrect sizing can lead to poor timekeeping. When selecting watch hands, the fit must be perfect to ensure smooth movement and functionality.
What Do the Measurements 1.35/0.85/0.20 mm Mean?
Understanding the numbers 1.35/0.85/0.20 mm in the context of the watch hands set is essential for anyone looking to work with this specific size. Here’s what each measurement signifies:
- 1.35 mm: This is the interior diameter of the minute hand hole. It refers to the size of the hole that fits onto the minute hand’s pivot post. This measurement is essential for ensuring that the minute hand fits perfectly and rotates smoothly around the watch dial.
- 0.85 mm: This is the interior diameter of the hour hand hole. The hour hand has a slightly smaller interior diameter than the minute hand, as it fits onto a different post. The difference in size ensures that the two hands do not interfere with each other during movement.
- 0.20 mm: This is the interior diameter of the second hand hole. The second hand typically has the smallest hole diameter because it is often attached to a thinner post. This diameter ensures a tight, secure fit for the second hand, allowing it to sweep around the dial.
Each of these measurements is crucial for the proper functioning of the watch, and selecting the correct size ensures that the hands move freely without obstruction.
How to Choose the Right 1.35/0.85/0.20 mm Watch Hands Set for Your Timepiece
Choosing the right set of watch hands for your timepiece requires careful consideration of various factors, including the size and style of your watch. The 1.35/0.85/0.20 mm interior diameter measurements are often seen in modern wristwatches, but how do you know if this is the right choice for your specific watch?

- Dial Size: The size of the dial and the markers will also influence the choice of hands. A larger dial may require proportionally larger hands, while a smaller dial will need more delicate, precise hands.
- Watch Type and Style: The style of the watch—whether it’s a classic dress watch, a sports model, or a dive watch—can impact your choice of hands. Some designs may require more elegant hands, while others may call for bold, robust designs.
- Material Compatibility: Watch hands are often made from materials like stainless steel, brass, or even lightweight aluminum. Make sure the material of your hands matches the design of the watch and the intended use. Some materials, such as brass, are more durable and resistant to corrosion.
