Identification and any possible help with the repair of this watch.

[NicElgin]

Hi, my name is Nick. I was gifted this Elgin watch when I was very young. It was dropped by my friend who didn’t know better at the time. I put off the repair because I didn’t feel it was necessary. I appreciate anyone who could help out in the identification of the watch and any parts they know are missing/broken. I can see that the casting for one gear is broken, however I have no idea what that gear is called. 
 

Thank you,

Nick

As it was dropped I expect its the balance staff that has broken. If so I have pointed out the balance wheel with a red arrow. It will need a new balance and I expect a good clean to get it back in good running order. Here is a site about Elgin watches, find the serial number and enter it and it will be able to tell you all about the watch you have.

Worth to mention, by alll means this is not a repair that an owner can do by himself. Will need to locate a reputable watchmaker. ACHI in the USA and BHI in the UK maintain an online directory.
