After months of anticipation, JIANGHUN Watch has finally launched a new watch series, the Deep Challenger JH02. This collection, centered on the themes of the ocean and the spirit of challenge, comes equipped with high-performance water resistance. The series debuts with two standard models, JH0201 and JH0202, both offering an impressive water resistance of 300m—sufficient for the needs of many enthusiasts.
In fact, the concept behind the JH02 series was inspired by the story of a renowned submersible that faced many challenges and overcame expectations to venture into deeper and deeper waters, eventually achieving success. From 1000m, to 3000m, 5000m, and 7000m, 300m is our starting point—this resilient spirit left a lasting impression on us, and the risks and efforts involved were unimaginable.

As you can see, the JH0202 is a derivative of the JH0201. It builds on the original dive watch design by adding a GMT function while maintaining the high level of water resistance. This might be particularly appealing to those planning to combine diving with long-distance travel.
The bezel features a rugged design with large teeth, offering a robust and secure feel. The spacing between the teeth is carefully crafted, providing excellent grip with a satisfying and effortless click. The bezel also incorporates an embossed stainless steel insert, enhancing the watch's depth and overall visual impact.
The crystal is sapphire, as you would expect, but unlike previous San Martin Watch models, JIANGHUN Watch uses a triple-layer transparent AR coating underneath, ensuring higher light transmission for better clarity in everyday use. There's no need to elaborate on the advantages of sapphire crystal—it’s one of the most exposed parts of a watch, and with a Mohs hardness rating of 9, sapphire is undoubtedly the best choice. If you're interested in learning more about watch crystal materials, Ben's article "Special Watch Crystals Scratch Tested: Hardlex, Flame Fusion & Krysterna" is a great resource.
The first dial released in the JH02 series features a classic black color—a staple of dive watches. While it may not be the most striking at first glance, it’s a fail-safe choice. The dial is matte with a wave-like texture, featuring a fine grain pattern that adds depth and subtle layers to the design. The 0, 6, and 9 markers incorporate elements from our brand, with contours inspired by the JIANGHUN logo.
Both models utilize C3 green luminous paint, known for its high peak brightness and long-lasting glow. The large area of luminous coating ensures that users can easily read the time in low-light environments, providing reliable visibility for night dives or dark settings.
The two models, JH0201 and JH0202, are equipped with the NH35A and NH34A movements, respectively. While some might wonder why we didn’t opt for higher-end movements, our goal is to offer more people the opportunity to experience high-quality products at a reasonable price. In this regard, the Seiko TMI-NH series, proven by the market, is the perfect choice.
Of course, JH02 will also see an advanced version released soon, featuring upgrades such as high-frequency Swiss movements, grade 5 titanium, better water resistance, and lighter weight. Stay tuned!
Now, let’s talk about the bracelet and clasp—this is where we've made the most significant improvements. For most brands, bracelets and cases are often produced by different suppliers, leading to inconsistencies in craftsmanship. This time, we established a dedicated team to bring bracelet production in-house, allowing us to communicate and refine the process continuously. The result is a significant leap in bracelet quality, and we can proudly say that the JH02's bracelet and clasp were custom-made for this model.
Originally, this watch was scheduled to be released in July, but we wanted to ensure it was perfected before its launch. Over the past few months, we've gone through countless adjustments and revisions. Now, the watch is finally ready.
Join JIANGHUN Watch as we embark on a journey of ocean exploration!
Thank you for watching!
