Got these from my grandfather. He loved to tinker with watches. I’ve kept a few and am selling off the rest. Hopefully you know more than me! I can see the movement working/hear ticking on three of them. 

This Lot of 4 Vintage/Antique Pocket Watches features hunter case designs and Roman numeral indices, perfect for collectors or enthusiasts of mechanical timepieces. The watches are sold as is for parts, with a focus on the craftsmanship and historical value of each piece. With a gold filled case material and a manual movement, these pocket watches exude a touch of elegance and sophistication, making them ideal for formal occasions or everyday wear. Ideal for those looking to restore or customize a vintage timepiece collection.

At least one of the watches is stamped 10k gold filled on the case. I believe all are gold filled.
