BESTFIT Mainspring WV99 for Vulcain caliber 120 Wrist Alarm - Alloy

BESTFIT Mainspring WV99 for Vulcain caliber 120 Cricket Wrist Alarm, white alloy. This is the ALARM side mainspring, not the Time side. See image for precise characteristics. 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.
