Arethusa Watch Co.

Arethusa Watch Co. takes its name and identity from HMS Arethusa, a Royal Navy light cruiser connected to founder Ethan Stansbury's grandfather Cyril B. Stansbury. The brand's World Diver is a travel-focused automatic dive watch with a Seiko NH35A movement, 200 m water resistance and world-time bezel functionality. Current official contact/FAQ evidence lists the company in Durham, North Carolina, while older official design copy references a Hartford, Connecticut workshop. Sources support U.S. design, testing and quality control plus manufacturing partners for components, but not in-house movement or full watch manufacture.
