BestCloneWatches.net Technical Archives · November 09, 2025 – Community-Verified Edition
Who Is XF Factory? (100 % Real Background)
- Founded: 2014 as KW Factory (Turkish-backed in Guangzhou)
- Rebranded: 2018 to XF after EU customs heat
- Current status: Active, but only releases 2–3 models per year
- 2025 specialty: Vintage Panerai with forced patina (PAM 127 “Fiddy”, PAM 441 ceramic)
- Key fact: XF is VS Factory’s “vintage division” – same owner, different branding for classic models.
XF doesn’t flood the market. They wait years, then drop one watch that makes every Panerai collector lose sleep.
