I realized that it's better to use EB/missing item. I need to say that the box from the parcel was in perfect condition and the box from the Apple Watch itself was opened and there was no watch inside?

Don't go Into anymore detail than you have to.

Simply say the watch was missing when the box was opened, and leave It at that.

I'm worried that they will ask me to name the IMEI and lock the device.

They already have the IMEI.

It's not often that companies place the IMEI In a pool of blacklisted numbers.
