Access & Availability
The wrist communicator, once an experimental device built in the secluded laboratory of Dr. Alistair Renshaw, quickly found its way into the hands of crimefighters, adventurers, and later, government operatives. As the technology improved, demand skyrocketed, and by the 1970s, wrist communicators transitioned from an exclusive tool of the elite into a consumer-grade product available to the general public.
Early Adoption: Crimefighters, Vigilantes, and Adventurers (1930s–1940s)
After Dr. Renshaw’s first Vox-Wrist Relay prototype in 1931, his patent rights on the technology allowed him to license and sell the technology to select buyers. Though the device was still expensive and unstable, it quickly found a niche among private detectives, masked vigilantes, and globe-trotting adventurers, many of whom saw the potential of a portable communication device that did not rely on wires or large radio towers.
By 1935, several well-funded individuals and organizations acquired custom-built versions of the Vox-Wrist Relay. These included:
Masked Vigilantes & Urban Crimefighters – Wealthy crimefighters and private investigators used modified wrist communicators for covert communication, emergency distress calls, and tactical coordination.
Globe-Trotting Explorers & Adventurers – Archaeologists, treasure hunters, and explorers purchased early models to stay in contact while navigating remote jungles, deserts, and mountains.
Wealthy Industrialists & Tech Enthusiasts – A small number of wealthy individuals, fascinated by cutting-edge technology, ordered custom-made versions despite their impracticality.
Though these early devices were unreliable and expensive, they provided a glimpse into the future of wearable communication.
The Technology Advances: Government Spies & Elite Operatives (1940s–1950s)
With the onset of World War II, many classified military research projects began working to miniaturize and improve radio communication for covert operatives. Government intelligence agencies saw the potential of wrist-mounted communicators, and through a mix of internal development and Renshaw’s patent licensing, the technology was integrated into elite military units and espionage programs.
By 1943, the first government-issued covert wrist communicators were being used by:
Allied Forces Special Operations (AFSO) – Given to elite commandos, spies, and resistance leaders, allowing for covert transmissions behind enemy lines.
Secret Intelligence Agencies – The British, American, and Soviet intelligence agencies developed their own encrypted versions for undercover agents.
Superhuman Operatives & Government-Sanctioned Heroes – Many government-backed special forces, crimefighters, and early superhumans were equipped with secure wrist communicators for field missions.
While these devices were far more advanced, encrypted, and durable than their civilian counterparts, they remained restricted to military and espionage use. The public still viewed wrist communicators as a gloried walkie talkie toy from pulp serials and adventure comics rather than a real-world tool. By the 1950s, wrist communicators had become a staple of secret agents, super-spies, and classified military units, but their existence remained largely unpopular to civilians.
Commercial Expansion & Widespread Access (1950s–1970s)
While the military and intelligence communities continued refining the technology, Dr. Renshaw’s growing communications company, Renshaw Wrist Coms, continued developing civilian-grade versions of the wrist communicator.
Key Developments in Public Accessibility: 1955 – The first commercial wrist communicator prototype is revealed to the public at the World Science Expo. While still too expensive for mass production, it marks the beginning of commercial interest.
1962 – Wright-Tech and other tech firms begin competing with Renshaw Wrist Coms, further pushing innovation and lowering costs.
1968 – The first affordable wrist communicator models hit the consumer market, though still primarily used by business executives, law enforcement, and emergency services.
1970s – Mass production begins, and wrist communicators become available in department stores, electronics retailers, and catalog sales.
By the late 1970s, wrist communicators were no longer a specialized tool of heroes, spies, or crimefighters—they had become a common item for sale to civilians. The Modern Era: A Ubiquitous Communication Device (1980s–Present)
By the 1980s, the wrist communicator had nearly completely replaced pagers, walkie-talkies, and many traditional handheld radios for those with the money to spend on them. With every increasing technological advancement the first Digital Age Wrist Coms hit the Market in 1999 with features that were considered decades ahead of their time

Complexity
The evolution of wrist communicators from the early Vox-Wrist Relay to the modern digital models represents a dramatic shift in technological complexity. The earliest designs were crude, unreliable, and heavily dependent on external support infrastructure, whereas modern versions are miniaturized, autonomous, and seamlessly integrated into global networks.
Early Complexity: The First and Early Models (1930s–1950s)
The first functional wrist communicator, the Vox-Wrist Relay (1931), was a mechanically simple but technologically advanced device for its time. It consisted of:
A shortwave radio transceiver – A compact transmitter and receiver built into a metal wrist cuff with a small speaker and a morse-code key for sending messages.
An external power source – Early versions could not operate on internal batteries alone, requiring an external belt-worn battery pack.
Manual frequency tuning – Users had to manually adjust frequency dials, as the first models lacked automatic channel-switching or encryption capabilities.
These early devices suffered from severe limitations: Short battery life (15–30 minutes of use).
Limited transmission range (2–5 miles under ideal conditions).
Interference-prone analog signals that were easily disrupted by weather or other transmissions.
Fragile components, making them unreliable for heavy field use.
Despite these limitations, the military and intelligence communities saw their potential. By the 1940s, engineers began integrating miniaturized vacuum tubes and early transistors, allowing for: Stronger transmission power (10+ miles range).
Early encryption modules for secure messaging.
First-generation lithium-based battery cells, increasing operation time.
These improvements made wrist communicators viable for espionage, reconnaissance, and elite combat units, but they still required a network of relay towers, command centers, and manual frequency management to function effectively.
The Transition to Self-Sufficient Devices (1960s–1980s)

Discovery
The first recorded instance of a wrist-mounted communication device can be traced back to 1931, when eccentric inventor and radio engineer Dr. Alistair Renshaw unveiled what he called the “Vox-Wrist Relay”—a prototype that would lay the foundation for the modern wrist communicator.
Dr. Renshaw was a brilliant but reclusive scientist, known for his radical experiments in miniaturized radio transmission. In the late 1920s, he became obsessed with the idea of creating a fully portable communication device, one that could be worn on the wrist like a watch and used anywhere without the need for bulky equipment.
His interest was partly driven by an unsolved mystery—a series of strange radio signals intercepted on a private frequency, believed to be transmissions from either an unknown intelligence agency, a rogue inventor, or something even more mysterious. Renshaw theorized that if radio signals could be intercepted remotely, then a personal communication device should be possible as well.
Determined to prove his theories, he retreated to his personal laboratory in Chicago, where he began miniaturizing radio components, experimenting with battery efficiency, and developing new ways to transmit signals over short distances without external wiring.
By mid-1931, Renshaw had developed the first working prototype of what would later be recognized as the world’s first wrist communicator:
The first successful transmission occurred on August 17, 1931, when Renshaw managed to contact his assistant Philip Garner, who was stationed on the rooftop of a nearby building. Though the audio was filled with static, the words “Philip, can you hear me?” became the first-ever voice communication transmitted via a wrist-mounted device.
