https://www.ebay.com/itm/257390040836Why we think so?
This eBay listing features a Certina DS Action Diver Green 40mm HAQ Quartz Watch (C048.410.11.091.00) from seller "zam2648." The seller claims a feedback score of 100 on this listing and has reportedly sold over 10,000 items, mostly low-cost electronics. For this watch, 300 units have been sold at a fair market price of $475, with "pre-owned (good)" condition and original packaging/papers included. While the price is in line with reputable watch dealers (about $441–$485 elsewhere), there are strong signs of review manipulation and counterfeit product risk in the broader selling history of "zam2648." These include repeated generic 5-star reviews, suspicious reviewer profiles, and external forum complaints about shill activity and counterfeits — mainly in consumer electronics. No direct evidence links this specific watch listing to counterfeit activity or fake reviews, but the pattern remains concerning. Critical note: The seller does not accept returns, which is unusual for high-value items and means buyers take on extra risk. If you decide to proceed, take extra steps to verify authenticity and be cautious. 🛑
