Help; ELGIN 16S VS 12S "Click" to Login or Register 
Can anyone tell me if I can swap out jewels from a 12S to a 16S? This is a 1912 16S 17 Jewel with one cracked jewel. It is complete but cracked. It holds the 2nd wheel and I don't have a donor 16S jewel unless I can use a balance wheel jewel. Will a 12S fit? has anybody tried this?

I'm going to say no - you can't do that. In order to find a compatible jewel, you will need another 16s movement - even then pivot sizes vary between movements.

I suggest using elginwatchparts.com to find a compatible jewel. Find the part # based on grade, then, at the bottom of the screen with part #s, enter your part number for a cross reference. It will show which grades use the same part.
