My Grandad's pocket watch

An EB I dropped it after the Choir gig on Saturday evening :-( . It is working . I had the glass replaced a few years ago. They used a plastic glass which popped off when I dropped it, where it pinged to I have no idea ! No doubt is somewhere but being clear almost impossible to see ! . Will have to get it replaced before my next outing.
Will catch up on comments tomo.
