TEMP-RITE Mainspring for Unitas caliber 190 - 195 - Steel

TEMP-RITE steel mainspring for Unitas calibers 190 & 195 movement and perhaps others, 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.
