2-Way Wrist Radio

First Appearance:

January 13th, 1946

Created By:

Chester Gould

Introduced in January 1946, the 2-Way Wrist Radio was an invention of industrialist Diet Smith's son Brilliant. Like many of Smith's inventions, it was kept from the public marketplace and given over exclusively to the use of law enforcement.

The 2-Way Wrist Radio allowed for audio communication between 2 parties. It was powered by a strong atomic battery, and used an aerial wire that ran up the inside of the wearer's sleeve. It was considered vastly superior to bulky walkie-talkies or CB radio devices, and was used very effectively by Dick Tracy and the members of his department.

In 2011, Tracy and the MCU temporarily reverted to using 2-Way Wrist Radios so they could communicate without having their calls intercepted by the high-tech devices being used by Willie the Fifth and Flyface. Shortly thereafter, Diet Smith introduced the Wrist Wizard to the MCU.

In December 2016, Tracy's Wrist Wizard suffered an explosive malfunction which prompted Diet Smith to issue a safety recall. The Wrist Wizard was replaced by a wrist communicator that superficially resembles a 2-Way Wrist Radio, but with many of the equivalent functions of the newer design.


  • During the conception of the 2-Way Wrist Radio, Chester Gould reportedly consulted with engineer Al Gross, a pioneer in the field of wireless communication.
  • In June 1954, the radio was upgraded to increase the range from 500 miles to 1,000 miles, then again in 1956 to 2,500 miles.
  • In 1964, the 2-Way Wrist Radio was upgraded to the 2-Way Wrist TV.
  • Tracy gave his young son Joe an obsolete Wrist Radio, which Joe was able to use to call for help when he was abducted and held hostage by dognappers.
  • Similarly, Little Face was given an old-style wrist radio to use in gathering information about the second Mr. Crime gang.
  • In the 1990 Dick Tracy feature film, the 2-Way Wrist Radio was the invention of police scientist Bug Bailey, who used it in his surveillance of the criminal Big Boy. Its introduction was shown in the comic book tie-in by John Moore and Kyle Baker.
  • A version of the 2-Way Wrist Radio was featured in promotional material for the Samsung Smartwatch. The Wrist Radio was also frequently referred to in news stories regarding the debut of the Apple iWatch.
  • In 2016, the designers Ivory & Horn obtained the license to produce a functioning "Dick Tracy 2-Way Wrist Radio" watch, manufactured by the Longio Watch Company. The project was funded through IndieGoGo and was limited to a run of 1,000. The initial model functioned only as a watch, but plans were made for later versions that would be bluetooth enabled, allowing it to function as a communications device.
