[mothered]

The watch was 106 (EDITED: I forgot the exact weight) so under @mothered suggestion I went with eb. But they continued to tell that it was shipped correctly, packed correctly and by the carrier investigation they confirmed no damage was done to the package and so it could not have lost in transit or went missing from the package.

In the end it was successful by the way.

At the end of the day, It succeeded and that's all that matters.
