JIOS "SEIRAN"

The Japanese watch brand JIOS was founded in Ishiyama, Otsu City, Shiga Prefecture, the birthplace of Japanese watchmaking. The brand's goal is to promote high quality and Japanese craftsmanship worldwide.
All components are 100% made in Japan, including the leather straps.

JIOS 's first model , the "SEIRAN," boasts a sophisticated, classic design that looks stylish and elegant on the wrist. The watch combines Roman numerals with bar indices for optimal legibility. A date display enhances its everyday suitability, while the guilloché dial with its fine texture makes it a perfect choice for a variety of situations—from business meetings to dinner.

JIOS SEIRAN – now in the color “Biwako Blue”

The first model SEIRAN from JIOS (ジオス) appears in a new color: “Biwako Blue” – inspired by the deep blue Lake Biwa , one of the most beautiful lakes in Japan, located in Shiga Prefecture.

In Japan, Lake Biwako is called "Biwako" – "ko" (湖) means "lake." In German, the term "Lake Biwa" is analogous to "Lake Baikal" or "Lake Geneva." JIOS deliberately uses the original name "Biwako" to preserve the authentic cultural connection to the region.

In Japan, blue is traditionally considered the color of luck – and JIOS aims to convey precisely this feeling with the color "Biwako Blue." The initiative to promote products from the region as "lucky, blue items" is known as Blue Ripple .

Instead of calling the color Ice Blue like many other manufacturers , JIOS deliberately chooses the name “Biwako Blue” to strengthen the regional identity and promote the awareness of Shiga and Lake Biwa worldwide – through the medium of the wristwatch.

The three-dimensional indices and high-quality materials give the watch a sophisticated look that appeals to users of all ages. The quality of the materials used is particularly noteworthy. The SEIRAN is equipped with a Japanese Citizen Miyota movement, and both the front and back are made of scratch-resistant sapphire crystal. With a case diameter of 38 mm, the watch sits perfectly on the wrist without appearing overly bulky. Another highlight is its versatility, as it can be worn stylishly both everyday and on special occasions.
