The beacons shining light on the Choptank River stand today as sentinels of maritime history & industrial innovation in the Chesapeake Region. Having guided sailing schooners such as the Pride II, skipjacks, and steamboats through the shallow waters since the industrial boom. Reproduced years later to serve as a visual icon of local revitalization. The CHOPTANK E250 delivers the unique presence and utility of these beacons to the wrist while telling the story of American industrial pastime.

The 7751 caliber automatic movement (also used in the Mission Moon & Cockpit Moon) was remastered by Hartwig Balke to achieve chronometer-grade accuracy and allow for simplified operation of the day, date, month, 24-hour, 12-hour, moonphase, and chronograph counting functions. Each movement was reconstructed through 2021 - 2022 with the aid of TWC apprentice watchmakers.
