Wyler Genuine Mainspring for ETA caliber 1120 to 1132 - Alloy

Wyler Genuine Material Mainspring for ETA caliber 1120 to 1132 movements, which includes several Wyler marked movements, P/N WM212, alloy, new in envelope. See image 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.
