In the world of top-tier sports watches, a masterpiece like the Clean Factory ceramic bezel is not just a functional scale, but the visual soul of the timepiece. One of the core technologies that has earned Clean Factory its global reputation is its almost exacting mastery over High-Tech Ceramic. Today, we will deeply dismantle the evolutionary path of the Clean ceramic bezel, from raw powder to the finished product.

I. Reshaping Matter: High-Purity Zirconium Dioxide (ZrO₂) Sintering

Clean Factory utilizes aviation-grade, high-purity zirconium dioxide powder. The birth of a ceramic bezel is an intense battle of extreme temperature and pressure:

• High-Pressure Injection Molding: Ceramic powder is mixed with a binder and injected into a mold under thousands of tons of pressure to form the “green body” (blank).
• Extreme Shrinkage Sintering: The blank must be sintered in a high-temperature furnace at 1400°C to 1600°C for up to 72 hours. During this process, the ceramic volume shrinks by approximately 20% to 25%.
• Dimensional Control: This drastic shrinkage demands extraordinary mold precision. Clean Factory employs proprietary mathematical models to ensure the inner diameter of the sintered ring fits the watch case with micro-metric accuracy.

II. The Pinnacle of Color: Bi-Color Fusion Technology

For the GMT series, the dual-color bezels—such as the red/blue (Pepsi) and blue/black (Batman)—are universally acknowledged as the highest technical challenge in the industry.

• One-Piece Construction: Unlike low-end spliced products on the market, Clean’s ceramic bezel is a true single-piece molding.
• Infiltration Process: While the ceramic is still in a porous state, a specialized chemical impregnation process allows the second color to penetrate deep into the ceramic matrix.
• Color Transition: The ultimate challenge lies at the junction of the two colors. Clean Factory has achieved a smooth, seamless transition, solving the long-standing industry problems of “blackening at the red-blue border” or “blurred dividing lines.” Currently, Clean’s V4 Pepsi bezel perfectly replicates the subtle deep purple tint under specific lighting, matching the genuine visual feedback.

III. Precious Metal Vacuum Plating: Platinum PVD Coating

The filling process of the bezel scales dictates its long-term oxidation resistance.

• PVD (Physical Vapor Deposition): Clean has completely abandoned traditional paint filling, opting instead for vacuum plating using Precious Metal Platinum Powder.
• Anti-Blackening Technology: This process ensures the scales maintain a brilliant silver luster even after long-term exposure to sweat and seawater, resolving the common pain point where standard scales turn black after a few months of use.
• Depth and Clarity: The recess depth of every single marker strictly aligns with the original, delivering extreme three-dimensional depth even under macro photography.

IV. Diamond-Grade Polishing and Texture

Ceramic possesses an incredibly high hardness rating (often exceeding 1200 HV on the Vickers scale), second only to sapphire and diamond.

• Diamond Polishing: Only diamond abrasives can polish post-sintered ceramic. Through a unique multi-step polishing technique, Clean Factory imbues the ceramic ring with a warm, deep, jade-like luster.
• Anti-Fingerprint Coating: The specially treated bezel surface is not only highly wear-resistant and scratch-proof but also drastically minimizes the residue of greasy fingerprints.
