The German company polyWatch has developed three high-performance premium products especially for the treatment of wristwatches. A product each for glass, plastic and protective sealing.

What could be more beautiful for watch lovers than the feeling of wearing a flawless, new watch on their wrist? You can’t resist looking at you new watch all the time. A view that makes you happy. At least until the first scratches and marks disturb the beauty of bracelet and case of the expensive timepiece. That’s annoying, but no disaster thanks to polyWatch.

In fact, wristwatches are predestined for scuffs and scratches of all kinds due to their exposed position on the outer wrist. Especially if the watch is a faithful companion in everyday life and is not only taken out of the cabinet on holidays. But how do you get scratched watches and scuffed bracelets back to their former glory? The three polyWatch products in detail:

polyWatch Plastic Polish

The elegant folding box contains a 5g tube of the high-tech polishing paste, a perfectly matched polishing cloth and a step-by-step manual.

The polishing paste is applied to the scratched plastic watch glass and the polishing cloth is used to remove the scratch from the scratched glass at a 90° angle.

polyWatch Glass Polish

Speaking of jewelry, polyWatch Glass Polish contains microscopic diamond grains that ensure professional results in the treatment of small and medium scratches in mineral and sapphire glass. The clever all-inclusive repair set also makes economic sense, because it preserves the value of the watch and is significantly cheaper than replacing the watch glass. And the set lives up to its name: a tube of repair paste, a tube of finish paste, a polishing rod, matching polishing strips made of fleece and a step-by-step manual leave nothing to be desired and ensure amazing results.

polyWatch Watch Protector

Prevent scratches in the watch glass in advance? Sounds almost too good to be true. But it is possible thanks to the polyWatch Watch Protector. The two-component system provides a protective film on the watch that protects against scratches, fingerprints and dirt. And that for up to 12 months. This is made possible by liquid glass technology with the futuristic name “Nano-Tech”. Everything needed for application is included in the elegant black sales packaging, which comes in a fashionable 6-counter display.

For jewelers, the products offer clear benefits:

– Because they are consumables, they increase frequency in your retail store.

– They are an easy way to realize additional revenue with good margins.

– They are perfect as bonus items or as a giveaway e.g. instead of a discount or for sales promotions.

Overview of our Buy-and-Sell products.

If you love your watch, you take care of it. Especially with lifestyle products like watches and jewelry, the topic of care cannot be neglected. In this blog article, you will find out what suitable cleaning of wristwatches looks like and how jewelers can profit from it.

If you finally invest in a luxurious timepiece after a long time of thinking and pondering, you’ll be happy to look after it even after you’ve bought it. A typical activity of watch lovers is the thorough cleaning of the wristwatch that is soiled with dust, sweat and dirt through daily wear. The hygiene aspect also plays a role. After all, the wristwatch should not become a hotbed of germs.

It should be clear to everyone that a luxury product from a jewelry store cannot be cleaned with dishwashing liquid and a kitchen towel. An effective but at the same time gentle cleaning agent is needed. The watch cleaning experts at PolyWatch have also recognized this problem and can now shine with an innovative new product.

With their Watch Cleaner, they have developed a multifunctional 3-in-1 care product for retailers. It frees the watch from unsavory deposits, cares for the material and then provides a noble high gloss. “Like new!” – you might think.

The attractive, matte-black folding box contains a whole range of practical helpers. This means unboxing with a wow effect. In addition to the high-yield spray bottle, the elegant folding packaging also contains a white polishing cloth, a gray microfiber cloth, and multilingual step-by-step instructions.

A must-have for the jeweler:

Each of the eye-catching and convenient counter displays contains 6 Watch Cleaning sets. And for the jeweler, the product is almost more practical than for the customer itself. Because with the Watch Cleaner, the jeweler not only satisfies a genuine customer need, but at the same time enhances his assortment and increases the average receipt of his customers. Before trying to sell the customer another piece of jewelry, one should first harvest the low-hanging fruits. This can be translated into practice, for example, with the Watch Cleaner and other buy-and-sell products from ERNST & FRIENDS.
