Introducing the new color "Biwa Trout Salmon" for JIOS's very first model, SEIRAN!The Biwa trout is an endemic subspecies found only in Japan’s Lake Biwa. During the spawning season, they are known to swim upstream in groups on heavy rainy days, which has earned them the nickname Ame-no-Io or Ame-no-Uo ("rain fish").In peak season, Biwa trout are prized for their rich, fatty flavor?comparable to premium tuna or salmon?and are especially delicious when enjoyed as sashimi.This color, often marketed as “salmon pink” by other brands, is currently trending. At JIOS, we chose the name Biwa Trout Salmon?just like our signature Lake Biwa Blue?to help promote regional recognition and support the branding of our local area in even the smallest way.
 
The "SEIRAN" is JIOS's first model, featuring a refined classic design that adds a stylish touch to your wrist. It is simple yet elegant, with a combination of Roman numerals and bar indices for easy readability, along with a date display for added functionality. The dial, adorned with a guilloche pattern, boasts a sleek, sophisticated form that makes it suitable for both business and casual occasions. The use of three-dimensional indices adds a sense of luxury, making it appealing to a wide range of ages, from younger individuals to seniors. We have carefully selected materials for each component, utilizing a Japanese movement made by CITIZEN MIYOTA and sapphire glass on both the front and back. The 38mm case size provides a perfect fit, not too large, and it offers a stylish look whether you're on or off duty.
Tochigi Leather is known for its supple yet durable nume (vegetable-tanned) leather?top-grade hide painstakingly produced by master craftsmen. Using methods that preserve the leather’s natural character, it develops richer colour and lustre the more you use it.
Please enjoy the way the leather “breaks in.” Nume leather softens and conforms to your wrist with continued wear. Its natural aging (patina) brings a deep, matured character that is uniquely appealing. One of the true charms of carefully made leather is how, over time, it shapes itself to its owner. Savour this evolving texture?with use, it becomes “leather that’s yours,” transforming into a one-of-a-kind item found nowhere else.
