Physical Vapour Deposition (PVD) is a vacuum process used to apply a very thin coloured or protective coating to metal watch parts. It creates a smooth, durable finish, but it is not scratch-proof and can wear over time, especially on edges and other high-contact areas. Avoid abrasives, chemicals and impacts, and clean the surface with a soft cloth.

No. Jowissa croco-style straps are made from calf leather embossed with a crocodile pattern. This creates the distinctive look of crocodile leather without using crocodile hide. Check the product specifications for the exact material of each strap.

No. Watches tested to 5 ATM are designed to withstand rain, perspiration and brief contact with water. They are not intended for swimming or diving. For water activities, choose a model with a rating specifically suited to that use and follow its product specifications.

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!

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.

On a Jowissa watch, “diamond cut” refers to precisely faceted glass or dial surfaces that reflect light like a cut gemstone. It describes the shape and finishing technique; it does not mean that the watch crystal is made of diamond.

Yes. Many Jowissa watches use interchangeable bands, and selected bands have a quick-release system that can be changed without tools. Other straps or bracelets may require a spring-bar tool or a watchmaker. Before ordering, check the band width and attachment type for your watch.

A Jowissa watch is tested for water resistance from 3 to 30 ATM, depending on the collection.
3 ATM: Watches tested to 3 ATM should not be worn while bathing or showering. They are built to withstand light rain, perspiration and brief contact with water.
5 ATM: Watches tested to 5 ATM are designed to withstand rain, perspiration and brief contact with water. They are not intended for swimming or diving.
10 ATM: Suitable for swimming and other surface water activities. Not intended for diving.
20 ATM: Suitable for swimming, water sports and recreational diving.
Always follow the water-resistance rating and product specifications for your exact model.

The name Jowissa is derived from the name of company founder Josef Wyss. He founded the business in Bettlach, Switzerland, in 1951, and Jowissa has operated continuously since then.
