The Guardian Spirit of Xuanwu
Dive watches are revered for their function-first ruggedness and reliability. Yet, at JIANGHUN Watch, we believe a superlative tool watch should equally serve as a vessel for profound cultural heritage. We are honored to introduce the all-new JH04 "Xuanwu" Series Diver, an embodiment of Eastern philosophy translated into modern engineering.

"Xuanwu", one of the ancient Four Symbols (Sì Xiàng) of the Chinese constellations, symbolizes unwavering resilience, comprehensive protection, and long-lasting health and vitality. The design essence of the JH0401 model is a direct reflection of these attributes, promising an enduring companion on your wrist.
The Art of Visual Balance
The JH0401 is built upon a profound exploration into the tenets of Chinese watch design. The focus was on achieving meticulous visual balance and the precise relationship between every design element. The result is a timepiece with inherently harmonious proportions and subtle detailing, imbued with a unique, enduring vitality.
Meticulous Case Finishing: An Art of Light and Dimension
The exterior of the JH0401 case is a testament to sophisticated craftsmanship, boasting remarkable dimensionality and a multi-faceted structure. Brushed and mirror-polished surfaces alternate sharply, creating a dynamic interplay of light and shadow that enhances the watch's sculptural quality. Crucially, the lines where each plane meets are sharp yet flawlessly transitioned, perfectly showcasing the high level of finishing expertise and the complex beauty of the structural design.

Color Selection
The three distinct dial variations offer different expressions of the Xuanwu ethos:
| Style | Key Feature | Xuanwu Symbolism |
|---|---|---|
| Orange & White | Dual-Lume Functionality, Milky Base | Unwavering Resilience – Clarity in the darkest conditions. |
| Deep Sea Blue | Pure Enamel Texture Finish | Tranquil Wisdom – The calm, profound power of water. |
| Gradient Magenta | Sunray Pattern, Enamel Texture | Vitality and Longevity – A vibrant expression of life force. |
The Luminous Performance
Reliability in the deep starts with legibility. The JH04 series utilizes specialized luminous materials:
- Orange & White: Combines C3 green luminescence (primary surface) and orange luminescence (indices), creating a vivid, high-contrast, dual-color effect.
- Blue & Magenta: Feature BGW-X1 blue luminescence, providing a consistent, long-lasting blue glow, trusted by professionals.

Precision and Protection
The JH0401 is engineered for confidence in demanding environments. This begins with its integrated protective elements, which are clearly defined in the technical specifications below.
The crown and guard structure is engineered for an extremely compact, streamlined profile. This minimalist design, while enhancing the aesthetic, results in limited operational space. We advise users, especially those with larger hands, to proceed slowly and carefully when screwing down or unscrewing the crown. Please consult the accompanying video for the suggested handling method to ensure smooth and convenient operation.
