The emerald cut is a sophisticated and elegant shape defined by its rectangular silhouette and cropped corners. Unlike brilliant cuts, the emerald cut is a "step cut," meaning its facets are arranged in parallel lines. This creates a mesmerizing "hall of mirrors" effect, producing flashes of white light rather than all-over sparkle.

Originally developed for cutting emerald gemstones to prevent chipping, this style became a hallmark of the Art Deco era. It is prized for its vintage charm, architectural lines, and understated luxury.

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

Yes, quartz watches are known for "high accuracy." Because the quartz crystal vibrates at such a stable and high frequency, they are typically much more accurate than mechanical watches, often varying by only a few seconds per month.

It works through a circuit: a battery sends electricity to a quartz crystal, causing it to oscillate (vibrate) 32,768 times per second. A microchip detects these vibrations and converts them into regular electric pulses (one per second). These pulses drive a stepping motor, which turns the gears and moves the watch hands.

A quartz watch is a timepiece powered by a battery rather than a wound spring. The "quartz movement" refers to the internal engine of the watch, which uses a tiny crystal of quartz mineral to regulate time. This crystal vibrates at a very precise frequency when electricity is passed through it, ensuring high accuracy.

Measure your wrist circumference, then compare the case diameter and strap length in the product specifications. Case shape, lug-to-lug length, thickness and personal style also affect how a watch wears, so diameter alone is only a guide. A smaller case usually looks discreet; a larger case makes a stronger statement. Choose the proportions that feel comfortable and suit your style.

A watch may be labelled “Swiss Made” only if it meets Swiss legal requirements. Its movement must be Swiss, the movement must be cased in Switzerland, the completed watch must be inspected in Switzerland, and at least 60% of the manufacturing costs of the watch as a whole must be generated in Switzerland. Jowissa watches are assembled and quality-controlled in Bettlach, Switzerland.

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.

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. 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.

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.

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.

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.
