Vintage Ladies Or Child's Watch- Bulova - Untested Small Silver Tone

This watch does have some adjustment to the wrist strap it can get slightly larger but it still seems very small and did not fit on my hand I had trouble working the hinge clasp thing but I think I just don't understand how it works it seems to have like a rope band with silver accents and then the face has a curved glass part you approaching this item as is I do not know if it would work

I could move the hands
