i contacted them in chat, they asked for photos of the box and started an investigation with the relevant department and it can take up to 1-2 weeks

Comply with their request for the photos, It will not Impact your claim.

To give you more informations as possible.

I contacted them and they asked for photos but due to barrier languages i sent photos only for the external package totally empty.

Then  they asked me to show also what was inside to show that the watch wasn't there.
I did it but with the watch box closed.

So they asked me to send it opened to show the watch isn't there,
I was about to do it but the chat disconnected and reconnected.

The following rep asked me for a photo of the label.
When i was doing it it disconnected.

Although It may appear coincidental, It's no fault of your own that the chat sessions terminated at the time of attempting to provide the photos, so I wouldn't worry about It.

The last rep told me to wait for the investigation but ended up in not asking the previous photos.

So i sent them only the first three photos.
Can it be a problem?

The claim's status Is taken from the last point of communication, so It shouldn't be a problem

Do I to recontact them and told this or without contact to send them to the email they gave me?

I'm not sure what you're referring to.
