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.

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.

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.

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.

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.

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.

No. Jowissa watch crystals are made from materials such as mineral glass or sapphire crystal, depending on the model. “Diamond cut” refers to the faceted shape and finishing technique, not to the material. Check the product specifications to see which crystal your watch uses.

No. A watch tested to 3 ATM is intended for light rain, perspiration and brief accidental contact with water. It should not be worn while swimming, bathing or showering. Always check the rating in the specifications for your exact model.

Selected Jowissa models use genuine diamonds as dial markers when “Diamonds” is stated in the product specifications. A “diamond-cut” glass, however, describes a faceted shape and finishing technique; it does not mean the glass contains diamonds. Check the specifications for your exact model.

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.

Edelweiss is an Alpine flower traditionally associated with courage, devotion and the mountain landscape. For Jowissa, it is a natural symbol of the brand’s Swiss roots and its home in Bettlach, Switzerland.

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.

A mother-of-pearl dial is crafted from the iridescent inner layer of certain mollusk shells, primarily oysters and abalone. This natural material is prized for its unique visual properties, exhibiting a shimmering play of colors that can include whites, creams, pinks, blues and greens. The exact hues and patterns vary from one piece to another, making each mother-of-pearl dial truly individual.  

What makes a mother-of-pearl dial special is its inherent beauty and the way it interacts with light. The nacreous structure of the shell refracts light, creating a subtle, dynamic luster that shifts as the viewing angle changes. This gives each watch dial a distinctive and luxurious character.  

At Jowissa, we often feature mother-of-pearl dials in our ladies' collections to enhance the elegance and sophistication of our timepieces. The natural iridescence complements our design aesthetic, adding a touch of unique artistry to each watch. Due to the organic nature of the material, every Jowissa watch with a mother-of-pearl dial is a one-of-a-kind piece, showcasing the beauty of the natural world.
