Wyler Genuine Mainspring for ETA caliber 2450, 2451 Automatics - Alloy

Wyler Genuine Material Mainspring for ETA caliber 2450, 2451 automatics which includes several Wyler marked movements, alloy, new in open envelope. See images for precise mainspring specification. While it says Genuine Wyler Material, Wyler didn't really make anything - they sourced movements & parts from various Swiss makers, but they did package their parts to sell to fix those movements. 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 an adequate job of representing the item.
