Once a quiet competitor, Clean Factory has officially taken the lead in the replica game. While QF Factory once made waves with its transparent caseback design, Clean has now responded with a full-on upgrade—combining premium materials, movement precision, and unmatched finishing. The result? A refined, ice-blue Daytona that pushes the boundaries of what a replica can achieve.
904L Steel and Sapphire Crystal: Built Like the Real Thing
Clean uses real 904L stainless steel—the same material used by Rolex—which offers superior corrosion resistance and a rich luster that holds up under sweat, salt water, and daily wear. The case is hand-polished through multiple steps, giving it a smooth, wrist-friendly finish you won’t find in lower-end replicas.
The dial is covered with a scratch-resistant sapphire crystal, treated with double anti-reflective coating for 92% light transmission. It feels premium, and it reads clearly even in harsh lighting. The ice blue dial itself features a soft gradient, paired with 3D Roman numeral markers and upgraded luminous paint for better visibility in the dark.
Design Highlights: See-Through Caseback and Ceramic Bezel
One of the standout features is the transparent caseback—a first for Clean’s Daytona lineup. Not only does it allow a full view of the upgraded 4131 movement, but it also features laser-etched details and polished finishing that mimics the original closely. Even the engraving on the lugs and rotor is sharp and deep—no shortcuts taken.
The ceramic bezel is crafted with nano-sintering tech, offering tight integration between the bezel insert and case. It’s highly scratch-resistant, and the engraved numerals stay crisp over time. The signature Oyster bracelet with brushed finish and an adjustable Easylink clasp rounds out the look. Clean even upgraded the clasp to a matte texture for better scratch resistance and grip.
Performance: An Upgraded 4131 Movement Under the Hood
At its core is Clean’s modified 4131 automatic movement. While most replicas use standard Shanghai 4130 or similar, Clean upgraded the balance wheel and hairspring, fine-tuning the accuracy to within ±3 seconds per day. Power reserve hits around 48 hours in testing, and thanks to an improved winding rotor design, the watch charges faster during wear.
We ran stress tests in real-world scenarios: from freezing temperatures to extreme heat, and even during high-impact activity. The movement didn’t miss a beat. Shock resistance meets military-grade (MIL-STD-810G) standards, and timekeeping remained stable over a full 72-hour test cycle.
Final Verdict: Did Clean Just End QF’s Transparent Caseback Hype?
Without a doubt. Clean Factory latest Daytona isn’t just another homage—it’s a statement. From the polished case and sapphire display back to the upgraded movement and bracelet, this is a replica made for collectors who demand more than surface-level flash.
If you’ve been waiting for a super clone watch that finally bridges the gap between authenticity and affordability, the Clean Factory Ice Blue Daytona might just be your perfect match for 2025.
