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.

Reading a Roman numeral watch is simple once you know the three basic symbols: I (1), V (5), and X (10). The numbers 1 to 3 are written as I, II, and III. The number 4 is traditionally written as IIII on watches. From 6 to 8, you add I to V (VI, VII, VIII). 9 is written as IX (one before ten), and 12 is XII. This elegant style is the signature feature of the Jowissa Roma collection.

This is known as the "Watchmaker's Four." We use IIII instead of IV primarily for visual symmetry. On a round dial, the four characters of IIII perfectly balance the four heavy characters of VIII (8) on the opposite side. It also creates a harmonious pattern: the first four numbers use only I, the next four use V, and the last four use X. This classical tradition is kept alive in our Swiss Made timepieces.

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.

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.

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.

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.

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.

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. 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.

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.
