Montblanc boutiques check standard models directly on the spot free of charge; a sending in to customer service with photos and serial number is alternatively possible. The question of originality nevertheless arises frequently because boutiques are only located in cities with about 80,000 or more inhabitants, and a journey is in many cases disproportionate. In addition, sales staff in boutiques know mainly the current range, which is why their assessment is not always conclusive especially with older models. Remote diagnoses remain in any case of limited reliability.
