All watches produced have a case number, which is registered by IWC, before they leave the factory. This permits us for instance to provide you with an extract from the ledger, for which a charge is made, for watches more than 10 years old. Alternatively, the case number together with the model number will give us an indication of whether this could be an authentic IWC watch.

Only a physical check at our factory or by an approved IWC dealer will establish whether the watch is in fact authentic or a fake.

If the vendor is not prepared to tell you the number, you may wish to reconsider and ask further questions. Please be aware that all watches which leave the factory have a case number. Vendors must provide you with the number. If the number is no longer legible, the case can be opened by a watchmaker, preferably one of our authorized IWC agents and the number can be found on the inside of the back of the watch case.
