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.

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.

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.

An automatic watch movement, also known as a self-winding movement, is a mechanical movement that harnesses the kinetic energy generated from the natural motion of the wearer's wrist to wind the mainspring. This eliminates the need for manual winding, provided the watch is worn regularly.

The key difference between an automatic and a manual mechanical movement lies in the addition of an oscillating weight, or rotor, in the automatic movement. This semi-circular or shaped weight pivots freely on a central staff and swings back and forth as the wearer moves their wrist. This motion is then transferred through a series of gears to wind the mainspring, the energy source of the watch.

Key components specific to an automatic movement include:
- Oscillating Weight (Rotor): A weighted component that rotates with the movement of the wearer's wrist.
- Winding Train: A set of gears that transmits the rotational motion of the rotor to the mainspring barrel, winding the mainspring.
- Reversing Mechanism: A system, often utilizing pawls or gears, that ensures the mainspring is wound regardless of the direction in which the rotor spins.

Automatic movements retain the intricate mechanics and craftsmanship of traditional mechanical movements while offering the added convenience of self-winding. As long as an automatic watch is worn with sufficient frequency, it will remain wound and continue to function without manual intervention. If an automatic watch is not worn for a period, the power reserve stored in the mainspring will deplete, and the watch will need to be wound manually (typically by turning the crown) to restart.

Jowissa offers a selection of automatic timepieces that showcase the beauty and engineering of these self-winding movements. These watches provide a seamless blend of horological tradition and everyday practicality. We encourage you to explore our collection to discover the elegance and convenience of Jowissa automatic watches.

A mechanical watch movement is a purely mechanical system that powers the watch, keeping time through the intricate interaction of various components. Unlike quartz movements that rely on a battery and electronic circuitry, mechanical movements operate using energy stored in a mainspring, which is typically wound manually by turning the crown or automatically through the motion of the wearer's wrist.

The main components of a mechanical watch movement include:
- Mainspring: A tightly coiled spring that stores the energy to power the watch.
- Gear Train: A series of interconnected gears that transmit the energy from the mainspring to the escapement at a controlled rate.
- Escapement: A crucial mechanism that regulates the release of energy from the gear train, ensuring the hands move at a consistent pace. Key parts of the escapement include the escape wheel, pallet fork, and balance wheel.
- Balance Wheel: An oscillating wheel that, along with the hairspring, vibrates at a precise frequency, acting as the timekeeping heart of the movement.
- Hairspring: A delicate spiral spring that controls the oscillation of the balance wheel.

Mechanical movements are appreciated for their craftsmanship, the beauty of their intricate mechanics, and the absence of a battery requirement. They represent a long-standing tradition in horology and are often favored by watch enthusiasts for their heritage and the skill involved in their creation and assembly.

At Jowissa, while we also offer quartz timepieces known for their precision and convenience, our mechanical watches showcase the art and complexity of traditional watchmaking. These movements require regular maintenance, including cleaning and lubrication, to ensure optimal performance and longevity. The subtle sweep of the second hand, characteristic of many mechanical watches, is a visual indicator of the movement's intricate operation.

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.

Yes. Synthetic sapphire crystal is extremely hard and highly resistant to everyday scratches. It is not completely scratch-proof, however: materials of equal or greater hardness, including diamond and some abrasives, can still mark it. Check the product specifications to confirm whether a particular Jowissa model uses sapphire crystal.

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.

Yes, the length of our steel and ceramic bracelets can be adjusted to fit an individual wrist size. When you order with jowissa.com we shorten the bracelet for you free of charge. Optionally your local watch dealer may also offer the bracelet adjustment as a service.

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.
