Specimen from my personal collection.

Original case.

Familiar label.

Both variations were manufactured by Chugai workshop.

 

Second possible seller /or manufacturer/ of these watch fobs has recently become known.

Akiba medals, Tokyo https://asiamedals.info/threads/badges-and-watch-fobs-made-by-akiba-medals-tokyo-akiba.21820

But watch fob stamp are identical to the stamp of Chugai workshop.

Was it some kind collaboration between these two Tokyo-based workshops (like here https://asiamedals.info/threads/regular-membership-badges-of-saiseikai.23745/#post-349320) or something else?

 

It's what's underneath the coating.
