The engine of a Shinola watch is the Argonite movement—a uniquely U.S.A. movement that is produced in our Detroit factory from nearly four-dozen Swiss-made parts. The complex assembly of each movement—a process that hasn’t been undertaken at this scale in the US in decades—requires highly-trained craftspeople skilled at manipulating miniature parts utilizing custom-made tools and optical magnification equipment. The movement is tested at every step of assembly to ensure it’s performing to stringent specifications.
Once the movement is tested, it gets attached to the dial, the hands are set, and it’s secured in a stainless steel case. Then the case gets closed and the backplate is attached. Each fully-assembled watch undergoes pressure testing to check for an atmosphere-proof seal and proper fitting of the stainless steel case, gaskets, and sapphire crystal. Following mechanical testing and a close visual inspection, the watchcase is fitted with high-quality straps of US-made Horween leather or stainless steel. The end result is a beautiful timepiece that is built to last, and built right here in America.
