【Unused】Chocobo's Mysterious Dungeon 2 Alarm Clock

Details of acquisition are unknown.
(I believe it was purchased at the Tokyo Game Show or Jump Festa, but I couldn't find any information... please let me know if you know.)
The watch is unused, but the packaging is in poor condition with noticeable damage.
It is as shown in images 4 and 5, and other sides are similar.
Also, when checking the battery compartment for this listing,
I found that a rusted battery was still inside, even though it's unused.
The contact metal parts were clean, so I don't think there will be any issues, but there is some color transfer in parts (image 6).
I will dispose of the battery and ship it.
Please consider if you are interested.
