Today’s pick is my MoonSwatch Mission to Mercury on a NATO strap. The orange on the strap represents “International Orange”. NASA uses "International Orange" for launch and entry suits (like the Artemis II Orion Crew Survival System and shuttle-era ACES suits) because it is highly visible against the ocean and sky, ensuring quick rescue if astronauts bail out. The high-contrast color was adopted for safety following the 1986 Challenger disaster.
