Nivaflex II Mainspring E3L5 for ETA caliber 2360 - Alloy

Durober Nivaflex II mainspring No. E3L5 for ETA caliber 2360 plus perhaps other similar ébauche movements as well, alloy (ETA 2361 to 2364 and a bunch of other makers calibers), new in envelope. GR Ref 3202, see images for further details. Found in a stack of parts for the repair of Croton watches.  I specialize in hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
