As I said the correct one is from the official spec sheet 167gr

I understand that, but as per your comment below, you're questioning Amazon's listing - which suggests you're not certain on the Item weight.

I don't know if the 200gr on amz refers to the watch or watch+packaging

Given you're going by the spec sheet, you've answered your own question pertaining to Amazon. That aside, I had the EB/missing Item method In mind, but It's a tad too heavy. The DNA, wrong Item received or boxing method can be used.

Let's put one second in pause the SE on .it domain.
You have to excuse me for the confusion i'm creating between the two domain, but i've an update on .co.jp.
Today i received my two legit orders. In total on .jp i did tre legit orders each one for a small amount of euros.
The next order is the one i want to SE.

The problem is that i noticed for the three legit orders is that on the proof of delivery on dhl (.co.jp domain ships only with dhl) there is the sign of my doorman. Where I live all of the shippings are received by him.
Is this a problem for a DNA method? I don't want to put him in trouble.
