About Daylight Saving Time · Museum store

Museum store

Daylight Saving Time visitors tend to be curious about the things that mark and measure time. The shelf below is built around three themes that come up every spring and fall: clocks and watches that auto-adjust for DST, sunrise alarms and light-therapy lamps that help bodies cope with the shift, and a couple of timekeeping curios. Affiliate purchases through the links below support WebExhibits, as do purchases from our recommended books page.

Atomic and self-adjusting clocks

  • La Crosse 14-Inch UltrAtomic Stainless Steel Wall Clock

    La Crosse 14″ UltrAtomic Wall Clock

    La Crosse Technology · 404-1235UA-SS

    A modern dual-antenna upgrade to the classic atomic wall clock: locks onto WWVB in Fort Collins from inside steel-frame buildings, runs about five years on AA batteries, and re-syncs through every spring-forward and fall-back automatically.

  • La Crosse 12.5-Inch Cherry Wood Atomic Analog Clock

    La Crosse 12.5″ Cherry Wood Atomic Analog Clock

    Rome RM2308 Brass Garden Sundial
