[mothered]

I just sent a box with nothing but air.

A few days later i got an email confirming they had received My watch

Less than 48 hours later they sent a confirmation that a new watch has been sent as a replacement.

Evidently, they did not check the return and probably decided to write off the Item as a tax deduction.

sent them my serial on the watch i currently already own

As a matter of Interest, what does your watch weigh?
