Can anyone tell me anything about my pocket watch...?

[HelenB]

Hi All!
I've had this beautiful little pocket watch since I was a child. I've loved looking at it and wondering about it. Now I am a proper grown up, I would actually like to know something more about it, and maybe get it restored...?

Can any of you let me know where I could start, or anything about it? I've attached some pictures. It appear to be a Wilsdorf and Davies, serial number 424339.

Any help or signposting on much appreciated!!

I've attached some pictures- see what you think :-)
