Inspired by the mist-covered surface of Lake Biwa on a winter morning, "Biwa Lake Kasumi" features a refined blue-gray dial that captures the tranquil beauty of this seasonal landscape.
As cold air meets the warmer, moisture-rich atmosphere above the lake, a delicate mist forms and drifts across the water, creating a breathtaking and dreamlike scene. The watch evokes the serenity of standing quietly along the lakeshore, inviting you to enjoy elegant moments accompanied by the peaceful beauty of "Biwa Lake Kasumi."
To bring a fresh contrast to the subdued blue-gray tones, the GMT hand is finished in a vibrant sky blue. The result is a versatile color combination that is equally suited to everyday wear and formal occasions.
Distinctive and unlike anything commonly found from other brands, this unique colorway makes the GMT DIVER'S 104 a truly one-of-a-kind timepiece.
A unique expression of Japanese scenery and craftsmanship, created for those seeking something truly different.
 
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.
