In his ‘American Pocket Watches – Identification and Price Guide Beginning to End 1830-1999’ Roy Ehrhardt provides a potential clue to one aspect of the “Peerless” origin story, “Peerless (Made for Charles Wendell, Chicago) EA 454 – Illinois Watch Company – 18-size – 15 jewels – open-face – nickel – Model 3 – lever set – Railroad Grade”. Charles Wendell was a jeweler in Chicago who was a founder of Wendell Jewelry, which grew into the wholesale firm of Wendell & Hyman, which eventually went on to become Wendell & Company.
