This makes it a favorite among divers, outdoor adventurers, and collectors who value durability and mechanical craftsmanship.
History of the Hamilton Frogman
The Hamilton Frogman has military roots that date back to the mid-20th century. The original Frogman watch was developed for U.S. Navy underwater demolition teams, also known as frogmen. These elite divers required a reliable and highly durable watch that could perform under extreme underwater conditions.
Hamilton, an American brand that later became part of the Swiss Swatch Group, played a key role in producing military watches during wartime. The modern Hamilton Frogman Automatic pays tribute to this heritage while incorporating updated materials and Swiss automatic movement technology.
