If Laco is so inept at dealing with the intricacies of shipping watches all over the world, as you suggested, you would think that this forum would be rife with 'customs' complaints. I can only speak from my own experience; of all the watches that Laco has shipped me (I'm in Canada), there hasn't been one issue with how it was processed through customs. I guess I must have been really lucky then. Of course I can only imagine the numerous pitfalls associated with keeping abreast of the customs requirements of the one hundred or so countries that Laco must ship to. And when something does get hung up at a border, at least we can all safely assume that the fault will most certainly be Laco's. Just like the excellent customs agents and FedEx employees in Norway (and Singapore), I assume that their Canadian equivalents are incapable of mistakes that would result in unnecessary costs or delays in a parcel's delivery.
When a watch manufacturer screws something up - and they all do on occasion - I prefer to judge them by how they fix their mistakes and not that they made one in the first place. Of course in your case we'll never know how things would have been handled since you couldn't wait a few days to find out how Laco wanted to process your particular warranty issue. Had the normal warranty procedure been followed, perhaps your watch would have been handled differently from beginning to end and the mistake in the shipping paperwork would have been avoided. Unfortunately, we'll never know the full story regarding the circumstances behind your particular complaint as it's highly unlikely that Laco will post anything here in their defence.
Forums are often very similar to kangaroo courts; manufacturers are accused of all sorts of things before being summarily found guilty by their accusers. I understand that buyers can momentarily get caught up in the frustration of dealing with a broken watch, but I'm equally frustrated when those buyers turn that frustration into an unfounded and undeserved bashing of a manufacturer. If the disproportionate number of complaints that you find in watch forums represented an absolute truth about the state of watch manufacturing today, you can believe that there wouldn't be one single watch company left in business.
