Lake Biwa is a stunning blue lake located in Shiga Prefecture, Japan. The beautiful blue hue is known as a "color that brings happiness"?we call it Lake Biwa Blue. From Shiga to the world, we proudly present this joyful shade through our watches, hoping its “Blue Ripple” of happiness will spread far and wide.This color, often referred to as “Ice Blue” by other brands, is currently trending. At JIOS, we support efforts to promote Lake Biwa Blue globally and are proud to be part of this initiative. Through watchmaking, we hope to contribute in our own unique way to raising awareness of our local region and strengthening its brand identity. That’s why we chose to introduce this color under the name Lake Biwa Blue.
 
The "GMT Divers 104" offers water resistance strong enough to withstand the pressure at the deepest part of Lake Biwa. As JIOS’s second model, the "GMT Divers 104" is designed as a traditional diver's watch, showcasing its robust 200M water resistance, capable of withstanding depths of up to 104 meters, the deepest point of Lake Biwa. It is powered by a Japanese-made "SEIKO TMI NH34A" movement and features a mechanical automatic winding system with a GMT function that allows you to track a second time zone. The case is thoughtfully designed at 40mm, making it slightly smaller than typical diver's watches, ensuring a comfortable fit for everyday use.
