The oval cut is an elongated version of the classic round brilliant diamond. It features a similar facet arrangement—typically 57 or 58 facets—which gives it nearly the same level of fire and brilliance as a round cut, but with a unique, contemporary shape.

Because of its elongated form, the oval cut can create an optical illusion of greater size compared to a round stone of the same carat weight. It is also highly favored for its flattering aesthetic, as the shape tends to lengthen the appearance of the fingers or the wrist.

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

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.

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.

A watch can only be labeled "Swiss Made" if it meets strict legal standards set by the Swiss government. It requires that the movement is Swiss, the movement is cased up in Switzerland, and at least 60% of the production costs of a watch taken as a whole must from Switzerland. At Jowissa, we proudly assemble our watches by hand in Bettlach, Switzerland, ensuring every timepiece meets these high standards of quality and precision.

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 dress watch is an elegant, slim-profile timepiece designed to be worn with formal attire, such as business suits or evening wear. Unlike sports watches, dress watches focus on minimalism and sophistication.

For Men: It must be thin enough to slide easily under a shirt cuff (the "Cuff Test").

For Women: It often acts as jewelry, featuring refined materials or faceted glass to complement evening outfits.

Key Features: Simple dials, leather or mesh straps, and a lack of bulky buttons or bezels.

According to etiquette, a woman should wear her watch on the left wrist if she is right-handed. This traditional rule places the watch on the non-dominant hand to prevent damage and scratches from daily tasks. However, modern fashion is flexible: many women choose the wrist that best complements their other jewelry. If you wear a heavy bracelet on your left hand, it is perfectly stylish and practical to wear your watch on the right wrist to balance your look and avoid scratching the timepiece.

The ideal watch size depends on your wrist circumference and personal style. As a general rule, for wrists under 15cm, case diameters between 20mm and 30mm look most balanced. For wrists between 15cm and 17cm, sizes from 30mm to 35mm are ideal. For larger wrists, cases 35mm and above provide a bold look. Jowissa offers a variety of sizes, ranging from our petite 20mm mini models to our larger 45mm options for men.
