Ingraham Mainspring for Dollar Wrist Watches - Wrist, Premier, Pal, etc - Steel

Ingraham Mainspring for Dollar Wrist Watches such as the Ingraham, Wrist, Premier, Pal and perhaps similar Mens sized watches, often called Bracelet watches (hence the Brac on some envelopes) because the bands were usually metal bracelet style. distributed by Hammel, Riglander & Co in New York, O.R. #21, measures Dennison 18-1/2 x 7 x 13-1/2", hole end, steel. Could also very well fit in other dollar watches as well. I likely have several of these so the one you get may differ slightly from the images. 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.
