Step-by-Step Changing Rectangular Crystals on Watches


In essence, changing a rectangular watch crystal is a task of both significance and challenge. Highly crucial for maintaining the aesthetic appeal and functionality of a watch, a fresh, unmarred crystal enhances visibility while safeguarding the delicate dials underneath from potential damage. A scratched, cloudy, or shattered crystal can impede accurate time-reading, reducing the splendor and operational value of your timepiece. The nature of the rectangular crystal heightens the challenge of replacing it; the task requires immense precision and finesse, as replacing a rectangular watch crystal often involves more intricate steps than its round counterparts. The angular nature requires exact corner alignments that resist misalignment or damage during the installation process. However, with the right tools, a meticulous approach, and our comprehensive guide, you can successfully replace your watch’s rectangular crystal, restoring its original glory with each tick of the hands.

Understanding Rectangular Watch Crystals

Watch crystals are an integral component of a timepiece, serving as the clear barrier that protects the watch dial from dust particles and potential damage. Constructed from either plastic or glass materials, this feature allows users to conveniently read the time without the need for any sort of super vision.

When comparing rectangular watch crystals to those of other shapes, there are a few unique factors to bear in mind. From a design perspective, rectangular crystals offer a sleek and modern aesthetic, often utilized in timepieces that exude a touch of professional elegance. From a functionality standpoint, one might question if there are specific conditions that could cause more harm to rectangular-shaped watch crystals compared to others. This largely depends on the quality of the crystal material and external elements it’s exposed to.

Choosing the Right Replacement Crystal

Knowing and understanding how to measure and choose the correct size and type of your new rectangular watch crystal is key. The size of the replacement crystal should be slightly bigger than the watch case to ensure a snug fit.

But there’s more than size to consider. Not all watch crystals are created equal, and you’ll need to choose one that is best suited to your watch and lifestyle.Plastic, mineral glass, and sapphire crystal are three common choices.

Plastic, or acrylic, is light, less expensive, and can easily have scratches polished out. This makes it a sound choice if the original crystal isn’t easy to find or if you want to maintain an original look. Mineral glass, on the other hand, is quite durable and scratch-resistant than acrylic but tends to break before getting scratched. They are very ideal for watches that are frequently used outdoors.

Sapphire crystal is the most expensive among the three. It’s extremely scratch-resistant, making it the best choice for luxury watches. But keep in mind, sapphire crystal can crack under impact.

To sum it up, your selection should hinge on what works best for your daily activities and the aesthetic of your watch. Each type of crystal material has its pros and cons, which can greatly affect the performance and longevity of your timepiece.

Necessary Tools and Materials

Commence by gathering all the necessary tools and materials required for this job. You will need a Professional Watch Crystal Removal Tool, a versatile and crucial equipment that ensures a safe and seamless process. A base plate is also vital for holding your watch securely as you work. Next, add a wrench to your toolkit, an essential tool for the precise operation of loosening and tightening components during the replacement process. Of course, don’t forget your replacement crystal. Always ensure it’s just slightly larger than your watch case for a snug fit. Remember, it is preferable to have tension ring or gasket fit crystals as they require a watch crystal press for a secure attachment, enhancing the durability and longevity of your watch. Lastly, consider keeping an acrylic crystal in your kit. They are useful for easily polishing away scratches and maintaining the pristine nature of your watch, especially if the original crystal isn’t easily available.

“How can I identify if a rectangular watch crystal needs replacement due to wear or if it’s just superficial damage?”

To determine if a rectangular watch crystal needs replacement due to genuine wear or if it’s just superficial damage, first conduct a close visual inspection.
