POTOMAC

|

Ref. PO250-B

For researchers of American industrial history, the Potomac manual‑wind wristwatch resurrects the aesthetic of 19th‑century pocket watches and pays homage to the Baltimore & Ohio Railroad—the nation’s first common carrier and a catalyst of precision timekeeping. This piece is engineered around a hand‑wound movement and features styling cues drawn from railway chronometers used to keep trains on schedule. Assembled in Towson using Swiss and German components, the Potomac offers a wearable artifact of America’s horological and railroading heritage, inviting enthusiasts to carry a slice of that era on the wrist.
