Roma Swiss Womens Watch J2.001.M

The name Jowissa is a combination of the surname and lastname of the company founder Josef Wyss. He founded Jowissa in the village of Bettlach, Switzerland in 1951. Jowissa has been active and in business without interruption 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.

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

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.

A water resistance rating of 3 ATM indicates that your timepiece is splash-resistant. It is designed to withstand accidental contact with water, such as handwashing or light rain.

However, a Jowissa watch with a water resistance rating of 3 ATM is not suitable for swimming.

The water pressure encountered during swimming, particularly with arm movements or when submerged, can exceed the protection level of a 3 ATM rating. This can lead to water entering the watch case and potentially damaging the movement, which would not be covered under warranty.

For water-related activities, we recommend considering Jowissa models with a higher water resistance rating. You can find detailed information about the water resistance of your specific watch model in the product specifications on our website.

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!

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.
