Up for auction: vintage military style INGERSOLL RADIOLITE watch. This watch likely dates 1919-1921 (Ingersoll went bankrupt in 1921). Watch is in nice condition, but runs on and off (does not run much, is hard to get started). Nice example of an old Radiolite. This watch is almost the size of a small pocket watch. My guess would be 37-40mm. Made in USA!
