Hamilton went back to its own archives for this one: a faithful reissue of the FAPD 5101, the hand-wound navigator’s watch it supplied to U.S. Air Force flight navigators during Vietnam. It keeps the original’s honest 36mm case and no-date dial, and the run is capped at exactly 1,776 pieces to mark America’s 250th anniversary — a heritage reissue with an actual archival reason to exist.
