GENERAL RESSORT Compatible Charging Spring / Reverse Barrel Spring For Jaeger-LeCoultre Reverso 846-1

Hey watch enthusiasts and repair pros!

If you're working on a Jaeger-LeCoultre Reverso, especially the calibre 846-1, you might be hunting for this little guy.

It's a compatible charging spring—also known as a reverse barrel spring—made by GENERAL RESSORT.

So if your Reverso isn't winding like it used to or the mainspring isn't catching, this could be the fix.

It's brand new with tags, so it's ready to install.

Just a heads-up, it's a compatible part, not an official Jaeger-LeCoultre one, but it's designed specifically to fit that Reverso movement.

If you're doing a full restoration or just a simple repair, having this spring on hand is a lifesaver.

Keep those vintage watches ticking!
