This 35x42mm. Rado Diastar is an actual watch we leased to Mad Men for season 7. This watch may have been won by a secondary character on the show, but we really don’t know if it appeared on camera. The automatic movement is accurate after a recent cleaning. The Diastar is famous due to its scratch resistant case. This movement was cleaned 2 years ago and is accurately running. We will provide a certificate of authenticity confirming this watch was leased to Mad Men. Own a piece of Mad Men history.
