The Wintered Over Device is an attachment to the Antarctica Service Medal which is awarded to those service members who perform winter service tours in Antarctica.

The Wintered Over Device is bestowed to indicate the number of winters served on the Antarctica continent. The device is worn as a disk on the award ribbon and is issued in bronze for one winter service, gold for two, and silver for three or more winters of service. On the full sized medal a clasp is worn, issued in the same degree, inscribed with the words "Wintered Over".
