Found this Weird small watch at my granda closet
i'ts a certina brand (it has a C, and it's written Certina)
it's soo small, like the size of a fingernail!, it's spring loaded and still working..
it doenst have a strap only holes like for a necklace or somthing to tie on..
in the back i have weird numbers, looks like a serial code
did anyone recognize this watch?
