Because Clean Factory (CF) and VS Factory (VSF) watches command the highest collector demand in the world, low-tier street sellers frequently paste fake “Clean” or “VSF” stickers onto cheap $150 DHgate replicas (“fake Cleans”). How do experienced `r/RepTime` moderators and our SwissClone master watchmakers verify a 100% authentic factory batch during your 48-hour Video QC? By cross-referencing three hard-engraved identifiers: the 6 o’clock Rehaut Serial Prefix/Suffix, the 3-Digit Oyster/Jubilee Clasp Code, and the Dandong Movement Balance Bridge.
- 1. Stickers Can Be Faked—Rehaut Serials & Movements Cannot: Never rely on a monkey/panda sticker alone. Always verify the laser-etched serial number at 6 o’clock on the inner rehaut ring and the 3-character stamping inside the folding clasp blades.
- 2. VSF 41mm Submariner (126610LN / LV) Signature Serials: Authentic VSF 41mm Submariners use rehaut serial prefixes Q66T… and 2R9… paired with clasp codes 3VV or 1LQ.
- 3. VSF 40mm Submariner (116610LN / Hulk) Signature Serials: Uses rehaut serial prefixes K25…, K28…, or S29… paired with clasp code 7GJ.
- 4. Clean Factory GMT-Master II (DD3285) Signature Serials: V3 Pepsi/Batgirl batches use rehaut serial suffix …Y2L3 or …L6V6 paired with ARF-sourced clasp codes F6U, A9A, or 1NQ.

2. The Ultimate Proof: Balance Bridge & Regulator Arm Inspection
Even if a counterfeiter laser-etches a copied serial number onto a cheap case, they can never fake a Dandong (Peacock) VS3235, DD3285, or DD4130 movement—because Dandong holds exclusive supply contracts with VSF and Clean Factory! During our mandatory 48-hour QC protocol on watches like the VSF Rolex Submariner 41mm 126610LV Starbucks, Clean Factory Rolex GMT-Master II 126710BLRO Pepsi, and Clean Factory Rolex Daytona 116500LN, our watchmakers verify the authentic Dandong balance bridge geometry and Timegrapher lift angle before shipping.

Collector FAQ & Pre-Shipment QC Answers
Why do Clean Factory GMT-Master II and Datejust watches often have ARF clasp codes like F6U or ORV?
Because Clean Factory purchases its 904L Oyster and Jubilee bracelets directly from ARF (widely regarded as the best bracelet manufacturer in the industry)! Seeing an F6U, A9A, or ORV clasp code on a Clean Factory watch is 100% authentic factory specification.
Do factories ever rotate to a new serial prefix when an older batch sells out?
Yes—approximately once a year, Clean and VSF introduce a fresh random serial prefix/suffix on new CNC case batches. Our 45-Agent Inspection Council updates our QC database weekly whenever a new factory batch code drops.
