Celestial Sophistication

The Jowissa Octa Moon Phase Collection invites you to experience time through a celestial lens, blending geometric precision with the poetic allure of the night sky. Hand-assembled in Switzerland, these timepieces represent a harmonious marriage of traditional horology and contemporary design.

The defining octagonal case serves as a bold, structured stage for the intricate moon phase complication, which elegantly tracks the lunar cycle. Complementing this artistry is a dedicated date window, providing essential functionality for the modern professional. Jowissa’s signature faceted sapphire crystal - complete with colored metallization - acts as a prism, catching the light to create a brilliant, multi-dimensional display across the shimmering sunray dials.

Engineered for reliability, the collection is powered by a high-quality Swiss movement, ensuring every second is measured with absolute accuracy. From the supple texture of a calf leather strap to the architectural strength of a stainless steel bracelet, each watch is a testament to the Swiss Made standard of excellence. The Octa Moon Phase is more than a tool for timekeeping; it is a sophisticated statement piece for those who find inspiration in the stars and value the heritage of fine craftsmanship.

FAQ

What is a moon-phase complication?
The moon-phase indication is a device serving to visualize on the watch dial the various appearances adopted by the Earth's satellite in the course of a lunar cycle: it may be waxing, full, waning or entirely hidden by the shadow of the Earth - and thus referred to as a new moon.

These different phases are traditionally represented by a mobile disk bearing two diametrically opposite depictions of the Moon alternately appearing through an aperture. The latter is cut out so as to provide a visual simulation of the Moon's waning and waxing episodes. As soon as the first interpretation vanishes, the second instantly comes on the scene. Moon phases may also be indicated by means of a hand pointing to various symbols, or by a three-dimensional sphere spinning on its axis, and of which one half is light-colored while the other is dark.

The mechanical difficulty of moon phases lies in the unusual interval between two full moons. By the 20th century, this complication had become essentially a romantic feature.
What does "Swiss Made" actually mean?
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.
Is sapphire crystal scratch resistant?
Yes, it is highly scratch resistant.

Sapphire crystal is made from a synthetic form of sapphire, which is a very hard material. On the Mohs hardness scale, which measures the resistance of a material to scratching, sapphire ranks at a 9. Only diamond, with a rating of 10, is harder.

This high level of hardnes means that sapphire crystal is much more resistant to scratches from common materials like coins, keys, dust, and even accidental bumps against many surfaces.

However, it's important to know that "scratch-proof" isn't entirely accurate. It is still possible to scratch sapphire crystal if it comes into contact with something equally hard or harder, such as other sapphire materials, diamond jewelry, or certain abrasive materials.

In summary:
- Sapphire crystal is very scratch resistant due to its high hardness.
- It will withstand most everyday wear and tear that could scratch other types of watch crystals.
- While highly resistant, it is not entirely scratch-proof under all circumstances.

So, if your Jowissa watch has a sapphire crystal, you can be confident that it's well-protected against most scratches you might encounter!
