Wrist Space Invader: Celebrating the Glory of Casio’s Video Game Clocks This Year

o
I’ve been tidying up my attic for the past few weeks, primarily to ensure its contents don’t collapse the ceiling. However, I have a side quest. My most treasured possession at age 12 was the Casio GD-8 car race watch. This digital timepiece featured built-in racing games on a small monochrome LCD screen. The two large buttons on the front allowed players to maneuver left and right to dodge oncoming vehicles, keeping the game alive for as long as possible. I lost count of how many times it was confiscated by teachers, as I often lent it to the toughest boy in class for protection against bullies. As a socially awkward nerd, this watch was crucial for my survival. I’m quite sure I still have it somewhere, and my resolve to find it has been strengthened by recent discoveries about its value.

Casio began producing digital watches in the mid-1970s, striving to compete on price with technology borrowed from the computer industry. As the decade drew to a close, however, the market became saturated, prompting the company to explore new methods to entice buyers. According to Polygon in 2015, “Casio returned to its original philosophy upon entering the watch market.” Yuichi Masuda, senior executive managing officer and Casio Board member, elaborated: “Watches are not merely timekeeping devices.” He noted a shift toward multifunctionality, incorporating features like phone number memory and music alarms alongside time display.

At that time, Taito’s Space Invaders was a sensation in Japan. Consequently, in 1981, Casio launched the CA-90/CA-901—a thick calculator watch featuring a space-themed shoot-’em-up, where players shot numbers instead of aliens. “Our aim was to create a lifestyle where games could be enjoyed anytime and anywhere,” Masuda explained.

Was Casio inspired by Nintendo’s Game & Watch series? The iconic handheld games debuted in 1980 with titles like Juggler and Ball, paving the way for classics like Donkey Kong, which later influenced the Nintendo DS. However, Shinji Saito, general manager and chief producer for Casio’s Watch Business Unit, disagrees: “In 1980, when Casio launched the CA-90, we also released the MG-880, a gaming calculator allowing users to enjoy digital invaders. While Nintendo’s Game & Watch also launched that year, the CA-90’s concept stemmed from our own development philosophy prioritizing lightness, thinness, shortness, and low power consumption; we were not inspired by Nintendo.”

In fact, during this period, Casio was innovating with features like data banks, thermometers, and pulse checkers. “The entire range of ’80s watches was vast,” watch enthusiast Andy Bagley notes. “I’ve been collecting for years and still discover models I’ve never encountered before. There were hundreds, including touchscreen watches from the ’80s.”

Regardless, the CA-90 became so successful that it spurred a golden age of creativity in Casio’s R&D. Between 1980 and 1985, dozens of game watches were produced—an impressive feat given the limitations of LCD technology at the time, which could display only preset shapes and lacked computer graphics or real animations. Various racing games, shooters like Helifizer and Zoom Zap, and rudimentary platformers like Jungle Star and Hungry Mouse were among them.

Some entries were more eccentric, like Aero Batics, a stunt flying game, and Hustle Monira, which involved catching dinosaurs (as opposed to just dodging falling eggs). There were also basic football and golf simulations. Similar to Nintendo’s Game & Watch titles, these watches showcased visually simplistic game designs that felt like science fiction at the time.

Notably, it wasn’t just tech giants creating game watches in the ’80s. The U.S. company Nelsnick obtained a license from Nintendo to make watches featuring games based on Zelda, Super Mario Bros., and Donkey Kong. Additionally, Seiko had its own ALBA game watches throughout that decade. The most aesthetically outrageous models came from veteran toy company Tiger, which produced bulky LCD game watches in the early ’90s based on movie licenses and arcade hits like Double Dragon and Altered Beast. However, as technology advanced and preferences shifted, the portable gaming market exploded with the arrival of the Game Boy in 1989, effectively ending the Game Watch era.

Today, a thriving collector’s scene exists. “These watches are incredibly sought after and can demand high prices,” Bagley shares. “The downside is that they weren’t very durable compared to all-stainless steel models like the Marlin, so few have survived. In pristine condition, rare and collectible game watches can fetch hundreds to over a thousand pounds.” For collectors like Bagley, these timepieces serve as nostalgic treasures, evoking memories of a time when students were distracted by digital watch beeps rather than social media alerts. “This served as my personal reference guide for the latest models. I eagerly checked the clock section whenever a new catalog arrived to scout for innovations.”

The watch industry continues to take a keen interest in classic video game themes. In 2022, Timex released a limited edition Space Invaders Watch featuring the game’s iconic sounds, and earlier this year, Casio unveiled a collection of beautifully crafted Pac-Man watches, sending fans like me racing to their website’s booking section. For those of us who were nerdy kids in the ’80s, these timepieces felt like the predecessors to smartphones and Apple Watches. Thus, my quest to find my car racing watch is not about its monetary value. It represents a connection to my 12-year-old self, a shared nostalgia for everything lost along the way.
