BESTFIT Mainspring 103X for Hanhart caliber 35 Timer - Alloy

BESTFIT Mainspring 103X for Hanhart caliber 35 Timer, white alloy, new in possibly frail envelope. While only one caliber is shown, my resources suggest it does fit others as well. See image for precise characteristics and further helpful information. I likely have several of these so the one you get may differ slight 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 an adequate job of representing the item.
