Hamilton Model 23 Military Chronograph

Hamilton Model 23 WWII Military Chronograph

• The Combat Heritage: Own a piece of genuine WWII aviation history. The Hamilton Model 23 was a critical piece of equipment for Allied navigators, used to calculate flight positions and bombing runs with split-second accuracy.
• Military Specs: Built to the rigorous AN-5742-1 specifications, this watch features a signature “blackout” dial designed for maximum legibility in darkened cockpits.
• Mechanical Pedigree: Powered by the legendary 19-jewel Hamilton movement, it features a column-wheel chronograph and a high-grade bimetallic balance for temperature compensation—engineering that still holds up under modern scrutiny.
