The birth of every JIANGHUN mechanical watch begins with meticulous control over the quality of components. IQC acts as a sturdy gatekeeper, keeping any flaws at bay. Every part, whether it's the case, strap, dial, hands, or intricate movement components, must pass through these stringent screenings to ensure that every detail exhibits impeccable craftsmanship.
Surface quality inspection is akin to a microscopic review of details. Every aspect of polishing, brushing, electroplating, coating on the case, strap, dial, hands, and crystal must present a uniform gloss without any scratches, bubbles, or color discrepancies. Dimensions and shapes adhere to strict tolerance requirements and design specifications, showcasing the JIANGHUN's dual commitment to precision and aesthetics in the minutest details.
Luminescence testing is a promise to deep-sea adventurers. In the dark chamber, we examine whether the luminescent materials on hands, indices, and bezels are bright and clear, and if they glow for a sufficient duration to meet the timing needs in diving conditions. Only when they shine brightly in the darkness, akin to stars illuminating the deep sea, can they pass through this crucial checkpoint.
We employ advanced ultrasonic cleaning equipment to thoroughly remove oil, impurities, and machining residues from the surface of parts, allowing each component to enter the assembly hall in a clean and flawless state.
We meticulously apply specialized lubricants to moisturize the movement components smoothly, significantly reducing friction, enhancing operational efficiency and lifespan, ensuring that the heart of every JIANGHUN watch remains youthful and vibrant.
The mounting of the dial and hands resembles a masterful composer orchestrating a symphony on a musical score: the dial is meticulously secured onto the movement, its position analogous to placing each note precisely on the stave. The hands, akin to elegantly choreographed dancers, are deftly installed, their alignment with the indices executed with pinpoint accuracy to ensure both visual harmony and flawless functionality.
Components such as movements, crowns, crystals, case backs, and gaskets are cleverly embedded within the case, forming an impregnable waterproof barrier, ensuring that the watch can confidently withstand underwater environments.
A rigorous test for nearing completion works. In the waterproof sealing process, we rigorously inspect the sealing of various parts of the case to ensure proper installation of gaskets, followed by waterproof performance testing, simulating underwater environments, applying corresponding pressure to the watch, verifying its claimed waterproof rating. Whether it's static waterproof testing or airtightness checks, we maintain a scientific and rigorous attitude, ensuring that JIANGHUN watches remain watertight under extreme conditions, safeguarding the internal components of the watch.
Comprehensive and rigorous testing is a relentless pursuit of perfect quality. From function testing to accuracy testing, and then to power reserve testing, we conduct comprehensive examinations of every JIANGHUN watch.
Whether it's basic functions like time setting and date adjustment or complex functions like chronograph and annual calendar display, we verify each one by one, ensuring all functions operate smoothly without any glitches.
Multiple days and positions of strict testing ensure that the watch keeps precise time.
Power reserve testing ensures that the watch can run continuously in a fully wound state, meeting the nominal power reserve time.
Appearance inspection is the final checkpoint for beauty. With eagle-eyed sharpness, we scrutinize every inch of the case, strap, dial, hands, and crystal, ensuring that surface treatments, color consistency, absence of scratches, and dust are all perfect. Whether it's the fine-tuning system of metal bracelets or the hardness and scratch resistance of sapphire crystal glass, we adhere to the most stringent standards, ensuring that every JIANGHUN watch is meticulously crafted inside and out, flawless and perfect.
High standards and rigorous processes are JIANGHUN's eternal commitment to quality. From component selection to assembly testing, every step embodies the dedication and wisdom of craftsmen. Only watches that successfully pass all tests, after enduring numerous trials, can bear the badge of "JIANGHUN," leaving the factory and stepping onto the world stage. This is JIANGHUN mechanical watches, crafted with rigorous craftsmanship processes, exquisite manual skills, and an ultimate pursuit of detail, forging the exceptional quality and unique charm of every wrist art piece.
