This is an INGERSOLL watch. The dial says SWISS MADE. The case back says SHOCK RESISTANT and ANTI MAGNETIC. I received it a long time ago from a friend who likes watches, but I don't know much about this brand, so I don't know any details. I don't know if it's mechanical, hand-wound, or quartz. I think I could tell if it's battery-powered by looking at the case back, but I don't have the tools to do so. I have kept it as part of my collection, but I am selling it because my collection has grown too large. No operational guarantee. Please consider it as completely junk. - Brand: INGERSOLL - Color: Black - Features: Shock Resistant - Material: Stainless Steel - Characteristics: Anti-magnetic, Water Resistant Thank you for viewing.
