BESTFIT Mainspring WA46 for ETA 2375, Bulova 9AB, 9ABC, 10AUC - Alloy

BESTFIT Mainspring with attached bridle WA46 for ETA caliber 2375, Bulova caliber 9AB, 9ABC, 10AU, 10AUC automatic Felsa 700, 705 automatics plus perhaps similar ébauche watches, white alloy, new in possibly dirty envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may differ 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.
