Doraemon Vintage Watch Antique Wristwatch Collectible Timepiece Nostalgic Design

Doraemon wristwatch set of 5. These are amusement prizes and not for sale from Shogakukan. They are very rare and hard to find now since they are from over 20 years ago. All were displayed in a glass case, so there are minor scratches and dirt due to age.
Except for the yellow one, the case filters are still on. The case parts are in good condition.
For the 4 designs other than the pumpkin design, the buckle and stick are missing, so masking tape is applied to prevent the fixed strap from coming off.
The yellow one is also missing the back cover, so masking tape is applied.
They have been wiped and disinfected, but there is a stickiness peculiar to the material overall.
All are sold as junk items.
They are not currently working.
It is unknown whether they will work with new batteries, so they are sold as junk.
