Vigor TONGUE End Clock Mainspring for Arogno 22 / 24 N - 8 x 9 x 17" Long - T 170.4

Vigor Clock Mainspring, TONGUE End – Dennison 8 x 9 x 17" in Length, P/N T 170.4, steel, new in envelope. See images for precise mainspring specifications. Mainspring fits Arogno caliber 22 / 24N travel clock movements and quite likely others as well. I likely have several of these so the one you get may differ slightly from the images.  I specialize is hard to find watch & clock parts and all parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
