Rosegold Womens Watches

Physical Vapour Deposition (PVD) is a process where an exceptionally pure, solid coating material is used to generate an ionized metal vapour which forms a coating mixture with inert gases.

Through condensation, a thin layer is deposited onto the surface of the watch. The PVD process is carried out under a forced vacuum in a coating chamber. This procedure is one of the most modern and ecologically sustainable coating technologies. PVD coatings are highly adhesive, hard and abrasion-resistant. They are extremely smooth and particularly suited to coating watch parts. These coatings can be single-layer, multi-layer or can be applied in graduated layers. The layer thickness ranges from 1 to 5 microns, although in some cases, just 0.5 microns or 15 microns and more can be applied.

Depending on the initial material and the inert gas employed, a wide range of PVD coatings can be applied. Essentially, these fall into four main groups: nitrides, carbides, oxides and carbons (Diamond like carbon).

The transparent cover on your watch face, which is often called the crystal, is not made of real diamond. Instead, Jowissa watches use high-quality materials such as mineral glass or sapphire crystal for their watch crystals.

Real diamonds are very precious and have a high cost. If watch crystals were made from genuine diamonds, the price of the watch would be significntly higher.

The materials we use, mineral glass and sapphire crystal, are chosen because they offer good protection for the watch face, allowing you to easily read the time. Sapphire crystal is especially known for its excellent durability and resistance to scratches, even more so than mineral glass.

Therefore, while the crystal on your Jowissa watch is not a real diamond, it is made of qualitative materials selected for their clarity and protective properties, ensuring the longevity and readability of your timepiece.

Most of our Jowissa watch crystals are made with mineral glass. Think of it like the glass in your windows, but a bit tougher. It can handle everyday wear and tear pretty well and is more scratch resistant than regular plastic.

However, just like anything made of glass, it's not completely scratch-proof. Really hard or sharp things could potentially leave a mark.

For some of our more premium collections, we also use sapphire crystal. Sapphire is very tough! It's much harder than mineral glass and offers even better scratch resistance. You'll usually find this mentioned in the specific watch description if it has a sapphire crystal.

Let's summarize:
Mineral glass (most Jowissa watches): Good scratch resistance for daily use.
Sapphire crystal (some premium models): Excellent scratch resistance, very durable.

To keep your Jowissa Watch looking its best, it's still a good idea to be mindful of bumps and scrapes against hard surfaces.

A Jowissa watch is tested for 3 to 20 ATM water resistance depending on the collection.
3 ATM: Watches tested for 3 ATM should not be worn when bathing or showering. They are build to withstand light rain, sweat and brief water contact.
5 ATM: Watches tested for 5 ATM are made to withstand rain, sweat and short swims.
10 ATM: Short dives, swim and other water sports are ok
20 ATM: Deep Dives, swims and other water sports are ok.

Leather bands should not be washed with water. For cleaning your strap refer to your local watch dealer to get a special leather cleaning product.

The name Jowissa is a combination of the surname and lastname of the company founder Josef Wyss. He founded Jowissa in the village of Bettlach, Switzerland in 1951. Jowissa has been active and in business without interruption since then.

Jowissa's croco style straps are crafted from fine calf leather. These straps are designed to emulate the elegant appearance of genuine crocodile leather through a special embossing process that creates the distinctive crocodile pattern.

This choice of high-quality calf leather allows us to offer straps that are both aesthetically appealing and durable, while also adhering to ethical and sustainable practices. The embossed crocodile pattern provides the desired sophisticated look and texture.

A watch with a water resistance rating of 5 ATM (atmospheres) is suitable for everyday use and can withstand splashes, rain, and showering. According to ISO standard 22810, this level of water resistance signifies that the watch can withstand static pressure equivalent to submersion at a depth of 50 meters.

While a 5 ATM rating offers more protection than a 3 ATM rating, it is important to understand the limitations for swimming. The dynamic forces exerted during swimming, such as the movement of your arms through the water and the impact of diving, can create pressure that exceeds the static test conditions.

Therefore, while your Jowissa watch with a 5 ATM rating can tolerate brief immersion and splashes, we generally advise against wearing it for prolonged swimming or diving activities. Consistent exposure to these conditions may compromise the water-resistant seals and potentially lead to water damage which would not be covered under the warranty.

For regular swimming or more intensive water activities, we recommend considering Jowissa models with a higher water resistance rating, typically 10 ATM or more. These models are specifically designed and tested to withstand greater water pressure and are more suitable for such use. Please refer to the technical specifications of each Jowissa watch on our website for detailed information on their water resistance level.

A water resistance rating of 3 ATM indicates that your timepiece is splash-resistant. It is designed to withstand accidental contact with water, such as handwashing or light rain.

However, a Jowissa watch with a water resistance rating of 3 ATM is not suitable for swimming.

The water pressure encountered during swimming, particularly with arm movements or when submerged, can exceed the protection level of a 3 ATM rating. This can lead to water entering the watch case and potentially damaging the movement, which would not be covered under warranty.

For water-related activities, we recommend considering Jowissa models with a higher water resistance rating. You can find detailed information about the water resistance of your specific watch model in the product specifications on our website.

Mineral crystal, which is used in most Jowissa watches, is a type of glass that's been treated to make it a bit tougher than regular glass. Think of the glass in a smart phone screen – mineral crystal is similar to that.

Because it's treated, mineral crystal is more resistant to scratches than a plain glass window. It can handle everyday wear and tear pretty well, like little bumps and rubs against things.

However, it's not as hard as some other materials, like sapphire crystal. This means that if your watch rubs against something really hard, like certain types of rock or even another piece of glass with a higher hardness, it could potentially get a scratch.

Here's the main idea:
- Mineral crystal is more scratch-resistant than regular glass.
- It can handle most of the little bumps and scrapes you might have during the day.
- However, it's not completely scratch-proof, and harder materials can still scratch it.

So, while your Jowissa watch with a mineral crystal is pretty durable for everyday use, it's still a good idea to be a little careful with it to keep it looking its best!

Yes, it is highly scratch resistant.

Sapphire crystal is made from a synthetic form of sapphire, which is a very hard material. On the Mohs hardness scale, which measures the resistance of a material to scratching, sapphire ranks at a 9. Only diamond, with a rating of 10, is harder.

This high level of hardnes means that sapphire crystal is much more resistant to scratches from common materials like coins, keys, dust, and even accidental bumps against many surfaces.

However, it's important to know that "scratch-proof" isn't entirely accurate. It is still possible to scratch sapphire crystal if it comes into contact with something equally hard or harder, such as other sapphire materials, diamond jewelry, or certain abrasive materials.

In summary:
- Sapphire crystal is very scratch resistant due to its high hardness.
- It will withstand most everyday wear and tear that could scratch other types of watch crystals.
- While highly resistant, it is not entirely scratch-proof under all circumstances.

So, if your Jowissa watch has a sapphire crystal, you can be confident that it's well-protected against most scratches you might encounter!

The term "brilliant cut" in the world of diamonds refers to a specific way of cutting a diamond to maximize its brilliance, which is the amount of light it reflects back to the viewer. It's not just about the shape of the diamond, but also the arrangement and number of facets (the flat surfaces on a diamond).

Brilliant cut diamonds have a large number of facets, typically 57 or 58. These facets are strategically placed to capture light entering the diamond and reflect it back out. The round brilliant cut is the most popular and widely recognized.

Rather than diamond, Jowissa utilizes expertly cut mineral glass (for watches) and Austrian crystal (for jewelry), each piece faceted in the brilliant cut to capture and reflect light with exceptional brilliance.

The radiant cut is a beautiful and unique diamond shape that combines the elegance of an emerald cut with the brilliance of a round brilliant. It's a popular choice for those who want a diamond with a lot of sparkle and a distinctive shape.

Rather than diamond, Jowissa utilizes expertly cut mineral glass (for watches) and Austrian crystal (for jewelry), each piece faceted in the radiant cut to capture and reflect light with exceptional brilliance.

The princess cut is a very popular diamond shape. It is a square or rectangular shape with a brilliant cut, meaning it is designed to maximize light reflection and sparkle.

Princess cut diamonds were first created in the 1960s and have since become a classic choice for engagement rings and other fine jewelry. They are prized for their brilliance, fire, and scintillation.

Rather than diamond, Jowissa utilizes expertly cut mineral glass (for watches) and Austrian crystal (for jewelry), each piece faceted in the princess cut to capture and reflect light with exceptional brilliance.

The expected battery life is 2 to 4 years depending on external factors like heat and cold. Jowissa uses standard silver oxide battery cells in combination with high quality and low energy consuming Swiss quartz movements.
