The Benzinger Potomac is a 42mm manual-wind timepiece built in collaboration with Jochen Benzinger of Pforzheim, Germany, whose signature guilloché work defines the sterling silver dial. Engine-turned by hand on a traditional rose engine and framed by a frosted hour track with black Roman numerals, the dial reflects classical pocketwatch design rooted in American railroad history. Heat-blued cathedral hands and a large sub-seconds register at 6 o’clock complete the layout. Inside, the 6498 caliber is decorated and visible through a sapphire caseback. Named after the Potomac River beside Towson’s Maryland workshop, the watch embodies a transatlantic heritage—conceived by Hartwig Balke in Pforzheim and brought to life by Towson Watch Company in Maryland.

At the heart of the Benzinger Potomac beats the ETA 6498-1 hand-wound caliber, a direct descendant of the legendary Unitas pocket-watch movement. Its robust 36.6 mm diameter and slender 4.5 mm profile house a single-barrel mainspring that delivers approximately 46 hours of power reserve on a full wind, while 17 jewels and an 18,800 vph (2.5 Hz) beat rate ensure smooth, reliable timekeeping.
Every surface of the movement is treated as an artisanal canvas: rhodium-plated bridges and main-plate shimmer beneath traditional Côtes de Genève stripes, punctuated by the deep-cut “Towson Watch Co.” engraving infilled with 24 k gold. A swan-neck regulator, regulated across five positions in-house at Towson, enables ultra-fine rate adjustment, while heat-blued screws seated in polished chatons and fully hand-polished bevels (anglage) speak to the meticulous finishing applied by our watchmakers.

The Potomac name belongs to a long-running series within Towson Watch Company’s portfolio, rooted in the visual language of American railroad pocket watches. Early references like the original Potomac and Bay Pilot models emphasized cathedral hands, oversized sub-seconds registers, and classical Roman numerals—foundational features that persist in the current Benzinger edition. While the materials and techniques have evolved, the design DNA remains consistent: clarity, balance, and mechanical honesty.
Named after the Potomac River—a vital waterway that shaped the culture and industry of Maryland and the Mid-Atlantic—the collection is a nod to Towson’s local heritage. Co-founder Hartwig Balke, a German engineer and lifelong sailor, chose Maryland as his home for its connection to the Chesapeake and its historical role in American manufacturing. The Benzinger Potomac is the most literal expression of that transatlantic story: a German hand meets an American eye in a watch that reflects both its origin and intent.
Each Benzinger Potomac is individually numbered and recorded by Towson Watch Company. Built with a fully modular case architecture—including a screw-down bezel and threaded caseback—the watch can be completely disassembled, allowing each component to be refinished or replaced independently. This ensures the case can be restored over time without compromising structural integrity.
This is a collector-grade piece—traditional composition, independently made, and supported by a workshop capable of full movement service, re-regulation, cosmetic restoration, and part replacement under one roof. Every detail, from the heat-blued screws to the polished anglage, reflects techniques no longer standard in industrial watchmaking. Its proportions recall early American pocket watches, but the execution reflects modern standards of precision and longevity.
