Building on its expertise in the world of sports, Longines has expanded its HydroConquest collection with the new USA Exclusive HydroConquest, whose design elements pay homage to the United States, a country where so much significant Longines history has been written.

Deriving inspiration from the world of aquatic sports, the USA Exclusive HydroConquest watch includes special features such as:

  • - Polished, ultra-scratch-resistant ceramic insert on its bezel.
  • - Streamlined dial featuring the initials “USA” in the bottom right corner of the display.
  • - Luminous numeral “50” in the upper left corner of the bezel which pays further tribute to the 50 states.
  • - Engraved American flag motif on the case back continues the vibrant theme that defines the USA Exclusive HydroConquest.

This USA Exclusive HydroConquest also includes an additional rubber NATO strap that allows for two unique looks for this timepiece.
