Nivastar Mainspring G984 for LeCoultre Memovox caliber 489 ALARM side - Alloy

Nivastar Mainspring G984 for LeCoultre caliber 489 Wrist Alarm (Memovox) ALARM side, white alloy, new in envelope. See images for precise mainspring specifications.  I likely have several of these so the one you get may differ slightly from the images. 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.
