A nostalgic manual-winder that puts the feel of a pocket-watch right on your wrist. Inspired by the pioneers of modern-day railroad transportation that once walked our region’s grounds. The Potomac’s exhibition case-back presents a uniquely remade Unitas movement. A simple but effective caliber originally made for American pocket-watches prior to their conversion into wristwatches for railroad workers a century ago. Fast forward to the new millenium, and our watchmakers have repurposed it once again, but this time in effort to recapture the lost tradition of American watchmaking and horological design. The dial extends this patriotic theme with its railroad-era aesthetic, bringing fresh light to a period of time that glorified American industry and change. Functions include: minute, hour, and a seconds sub-dial at the 6 o’clock position.

The TWC Headquarters in Baltimore, MD overlooks the iconic B&O Warehouse, home of the original backbone for modern-day railroads. Our watchmakers drew from this timeless landmark to create the PO250, an instrument that commemorates the Chesapeake’s role in shaping American industry forever. The proprietary Unitas movement found within the 42mm polished steel case pays tribute to early innovations in American watchmaking, as an earlier version of this same movement was a breakthrough work of horological technology in the USA a century ago. The dial extends this patriotic theme with its railroad-era aesthetic. The PO250 paints a horological picture of this story, in which pocket watches evolved into wristwatches due to this railroad boom that all started right in our backyard. Like the B&O warehouse, the Potomac’s large presence serves as a constant reminder of our history and everlasting need for tradition.
