What is Casio? Understanding the Brand’s Legacy
The History of Casio: From Calculators to Global Icon
Founded in 1946 by Tadao Kashio in Tokyo, Japan, Casio began as a modest manufacturing business producing mechanical parts in the aftermath of World War II. The company’s journey to becoming a global electronics powerhouse started with an unexpected product: the “yubiwa pipe,” a hands-free cigarette ring that bankrolled the company’s early operations.
The real breakthrough came in 1957 when Casio released the Model 14-A, the world’s first compact all-electric calculator. This innovation revolutionized computation work and established Casio Computer Co., Ltd. as a technology pioneer. Throughout the 1960s and 1970s, the company expanded its calculator line, introducing the Casio Mini in 1972, which created the personal calculator market and brought computational tools into households worldwide.
In 1974, Casio entered the watch industry with the Casiotron, the world’s first digital wristwatch featuring an automatic calendar function. This marked the beginning of Casio’s dominance in digital timekeeping. The company continued innovating with the F-91W in 1989, which became the most sold wristwatch globally with an annual production of 3 million units. The legendary G-Shock series, launched in 1983, revolutionized the watch industry with its unparalleled shock resistance and durability.
Casio’s Core Values: Innovation, Durability, and Affordability
Casio’s success stems from its founder Toshio Kashio’s unique philosophy: “invention is the mother of necessity”. Rather than developing products based on user demand, Casio creates innovative solutions that generate new demand among users. This forward-thinking approach has led to groundbreaking products across multiple categories.
The brand’s commitment to durability is evident in every product. Casio watches undergo rigorous testing to withstand harsh conditions, earning them a reputation for reliability in demanding environments. From military personnel to outdoor enthusiasts, people trust Casio products to perform when it matters most.
Affordability remains a cornerstone of Casio’s identity. Unlike luxury brands that prioritize exclusivity, Casio makes quality technology accessible to everyone. A Casio F-91W costs just $15, yet delivers reliable functionality that rivals watches costing hundreds more.

Casio vs Competitors: How Does It Compare?
Casio vs Seiko: Which Japanese Watch Brand is Better?
Casio and Seiko represent different philosophies in Japanese watchmaking. While Seiko has established prestige through its Grand Seiko line and mechanical watchmaking heritage, Casio focuses on digital innovation, durability, and accessibility.
Seiko excels in mechanical movements and traditional craftsmanship, particularly in the luxury segment where Grand Seiko competes with Swiss brands. However, Casio dominates the quartz market, offering superior functionality and durability at lower price points.
For everyday wear and active lifestyles, Casio provides better value. The shock resistance, water resistance, and maintenance-free operation of G-Shock watches surpass most Seiko offerings in similar price ranges. Casio’s digital technology delivers more features—multiple alarms, world time, stopwatches, and timers—than traditional mechanical watches.
The choice between Casio and Seiko ultimately depends on preferences: those valuing mechanical craftsmanship and traditional aesthetics may prefer Seiko, while those prioritizing durability, functionality, and modern technology find better value in Casio.
Casio vs Citizen: Value and Technology Comparison
Citizen and Casio both emphasize technological innovation, though their approaches differ. Citizen’s Eco-Drive solar technology and mechanical watch offerings compete directly with Casio’s product range.
In the mid-range segment, both brands deliver excellent value. Citizen’s Miyota movements have become industry standards for microbrands and third-party manufacturers. However, Casio’s G-Shock line offers superior shock resistance and ruggedness compared to Citizen’s diving watches.
Citizen tends to focus more on traditional watch aesthetics with modern technology, while Casio embraces bold, contemporary designs that appeal to younger demographics. Casio’s calculator watches, digital displays, and gaming-inspired limited editions represent unique offerings without direct Citizen equivalents.
Price considerations favor Casio at entry levels, with models like the F-91W ($15) and DW-5600E ($50) providing exceptional value. Citizen’s comparable models typically cost more, though both brands offer reasonable pricing relative to their features and quality.
Casio in Pop Culture and Fashion
Celebrities Who Love Casio Watches

This durability-focused approach aligns with growing consumer awareness about sustainability and ethical consumption. By creating products that don’t require frequent replacement, Casio reduces resource consumption and waste while providing better long-term value to customers.
The brand’s commitment to repairability and parts availability extends product lifecycles further. Replacement straps, batteries, and components remain available for many models, allowing users to maintain watches rather than discarding them when minor components wear out.
