HOTCasio G-Shock G-100 Series | Analog-Digital Watch | Shock Resistant | 200M Water Resistant | Anti-Magnetic | Neobrite Hands | EL Backlight | Black

The Casio G-Shock G-100 is a study in doing more with less. Launched in 2000 and still going strong, it distills the G-Shock philosophy — toughness, reliability, legibility — into a medium-sized round case that manages to feel both classic and purposeful on the wrist. The all-black resin case and band give it a clean, no-nonsense look, while the analog dial with Neobrite luminous hands delivers the kind of instant time readability that digital-only watches can't match at a glance. This is a G-Shock for people who appreciate straightforward utility without compromise. Under the surface, the G-100 is built on the three pillars that define the G-Shock line. Shock resistance protects the movement and crystal from drops and impacts. Anti-magnetic resistance shields the movement from interference by magnetic fields — a real-world concern for anyone working near motors, speakers, or industrial equipment. And at 200-meter water resistance (20 ATM), it far exceeds what most daily wear watches offer — fully capable of swimming, snorkeling, and extended submersion well beyond everyday splashes. The electro-luminescent backlight with afterglow activates at the push of a button for instant display readability in low-light conditions, and Neobrite coating on the hands ensures the analog display glows in the dark for hands-free time reading. The feature set is intentionally focused. Dual time lets you track a second time zone simultaneously — practical for travel or remote work. The 1/100-second stopwatch covers elapsed time with precision up to 23:59'59.99"", and a daily alarm with hourly time signal handles basic scheduling needs. An auto-calendar and selectable 12/24-hour format round out a clean, no-frills package. Powered by a CR2016 battery rated for approximately 3 years and housed in a mineral glass-protected case measuring 49.6 × 47.8 × 15.7mm and weighing 65 grams — the G-100 is a watch that earns its place on the wrist every single day.

Casio

With the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.

Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.
