Alto Swiss Ladies Watch J4.367.L

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.

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.

Physical Vapour Deposition (PVD) is a process where an exceptionally pure, solid coating material is used to generate an ionized metal vapour which forms a coating mixture with inert gases.

Through condensation, a thin layer is deposited onto the surface of the watch. The PVD process is carried out under a forced vacuum in a coating chamber. This procedure is one of the most modern and ecologically sustainable coating technologies. PVD coatings are highly adhesive, hard and abrasion-resistant. They are extremely smooth and particularly suited to coating watch parts. These coatings can be single-layer, multi-layer or can be applied in graduated layers. The layer thickness ranges from 1 to 5 microns, although in some cases, just 0.5 microns or 15 microns and more can be applied.

Depending on the initial material and the inert gas employed, a wide range of PVD coatings can be applied. Essentially, these fall into four main groups: nitrides, carbides, oxides and carbons (Diamond like carbon).

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.

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.
