Elgin Mainspring for 6 3/4 x 8 ligne FF 60 & AS 1173 No. 6705 - Alloy

Elgin Mainspring for 6 ¾ x 8 ligne movements, #6705, automatic (tongue) end, alloy, new in envelope. The 6 ¾ x 8 ligne Elgin movements are FF 60 ébauche based so this mainspring will fit movements other than just the specified Elgin including the AS 1173. See image for further details. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item
