Even professional suppliers with disclaimer may, in Germany, generally not sell counterfeits; a disclaimer does not exclude criminal liability. The positive rating situation of such suppliers does not necessarily prove reputability, since the eBay verification seal can be imitated by HTML manipulation; the actual PostIdent procedure via Deutsche Post AG, by contrast, is built on identity-card basis and harder to fake. With watches especially the box (Montblanc uses black, not red boxes) is an indicator; a first counterfeit with a real automatic movement would already require a minimum calculation beyond 300 euros, which permits doubts about movement quality. Bidders should check supplier and auction behaviour critically and report violations to the trademark holder.
