What makes the Chicago 453 unique: Today, we are excited to introduce this remarkable piece from the Elgin National Watch Company — the Chicago 453. Originally manufactured in 1928 by Elgin, the Chicago 453 features a modern single-sunk dial, sleek type numbers, and a clear back, revealing the intricate nickel gears with gold accents. Our Diamond-Like Coating (DLC) case elevates the stylish dial and subdial with an incredibly durable and scratch-resistant coating. Powered by 17 ruby/sapphire jewels in screw settings, this 345-grade timepiece is truly timeless. Lastly, our Black leather strap brings the whole design together, giving the watch a classic, sophisticated look. This remarkable watch was originally produced in Elgin, Illinois, in 1928, when the 1st U.S. air-conditioned building, The Milam Building, opened in San Antonio, Texas.
