New Submariner- Clicking Noise

[rockff25]

I posted this in the general forum, but figured I should re post here.

I just purchased a new submariner and am concerned about a noise I am hearing inside the watch.

When the watch is held on its side with the 3 or 9 facing up I can hear a clicking noise like something is dropping from the 3 to the 9. When the watch is rotated the other way I can hear it drop back.

I had the bracelet taken off and it was still making the noise, so I have ruled that out. Has anybody heard of this before and if so what is it?

Thanks in advance!
