Hello and good day.

I need a mainspring for one of my prized watches. It's an Illinois Getty bridge model grade 186.

The catalog number is 6840. It would be great to have an alloy, as this will be my dress watch for the remainder of my life...

Thanks for reading! I'm hoping someone out there can give me a hand with this one!

Mainspring #6840 is the old number. The newer numbers (likely on alloy mainsprings) will be 47313 through 47317 (weakest to strongest).

Thanks Jerry!

Now that you gave me the correct parts number I found one right away!

Searching for 6840 led me to believe this was going to be a difficult search! Glad I was wrong!
