Goliath pocket watch project

[danybeany]

Hello everybody,I am a total novice and my current project is an extremely large goliath pocket watch 105mm dia.It was a wreck when I got it for very little money and I am learning from fiddling with it.Ive found out the bottom balance staff pin is broken,as its obviously been dropped,which caused its demise,.Anyway I think it's an omega ?,not to sure,but im trying to find out the calibre number so I can try and get a replacement staff for it and then maybe fit it to the balance wheel.Would any of you nice people be able to point me in the right direction please.

It would also be nice to have the diameter of the movement measured on the dial side and a picture of the movement on the dial side without the dial we need to see the setting components.

These are the pictures of the dial side of the watch,there is a number if it means anything.

Should be an Omega Cal. 99, 30‘‘‘

Well that is very interesting indeed,from what I have read,there are 3 x sizes in omega golieth watches 27'''  40'''  & 60''',does this sound correct,forgive me if I'm getting confused,any idea how I can determine which size watch I have here,of course I may be reading this wrong,as I am only an enthusiastic amateur.thankyou very much for the link

I‘m not the expert either but I‘d recommend searching this site to get an overview about the Goliath watches:

You will probably have to have a staff made.

Yes that's what I'm looking at next,trying to find a company that will do that if not the watch is for just display.
