G-Shock X-Large GA100

Items Description

The G-Shock X-Large GA100 is a tough analog-digital watch designed for users who need a large, legible display and dependable shock resistance in demanding environments. Its 55 x 51.2 x 16.9 mm case and 70 g weight place it in the oversized segment of the G-Shock range, while 200-metre water resistance and JIS Class-1 magnetic resistance support use in wet, muddy, and mechanically noisy conditions.

 

The GA100 pairs a resin case and band with mineral glass, steel pushers, and an analog-digital dial layout that combines large hands with LC display windows. Powered by a CR2016 battery rated for approximately five years, it stays focused on durability and long service life rather than frequent charging. The wide face supports quick reading at a glance, and the 145 to 215 mm band range accommodates a broad span of wrist sizes.

 

Key Advantages of the G-Shock X-Large GA100 Analog-Digital Watch with 200M Water Resistance and 1/1000-Second Stopwatch

 

1. Large Analog-Digital Dial for Fast Legibility

The GA100 places large analog hands over dual LC display windows, producing a hybrid layout that suits users who want both analog orientation and digital precision on one face. This design supports quick readings during sport, travel, or low-light work, and the oversized architecture keeps key information visible without needing to bring the watch close to the eyes.

 

• Hybrid Display: Analog hands paired with two LCD sub-windows.
• Dial Diameter: Roughly 35 mm face area for high-contrast readings.
• Readability: Clear at a glance under changing light conditions.

 

2. Shock Resistance and 200-Metre Water Resistance

Built around the core G-Shock shock-resistant structure, the GA100 protects the module from impact, vibration, and drop stress through a resin case, recessed dial, and reinforced bezel geometry. The 200-metre water resistance rating supports swimming, snorkelling, and surface water sports, and the JIS Class-1 magnetic resistance helps maintain accuracy near everyday magnetic fields.

 

• Shock Resistance: G-Shock core structure withstands impact and vibration.
• Water Resistance: 200 metres / 20 bar, suitable for swimming and snorkelling.
• Magnetic Resistance: JIS Class-1 rated against daily magnetic fields.

 

3. 1/1000-Second Stopwatch and Speed Indicator

The GA100 includes a 1/1000-second stopwatch with a measuring capacity up to 99:59'59.999'', aimed at training, competition, and interval work. A speed indicator converts elapsed time into average speed readings for a set distance, and the 12/24-hour format can be selected to match regional preferences. A countdown timer supplements the stopwatch for structured sessions.

 

• Stopwatch: 1/1000-second resolution up to 99:59'59.999''.
• Speed Indicator: Calculates average speed for a preset distance.
• Time Format: Switchable 12/24-hour display.

 

4. Long Battery Life and Daily Practical Functions

A CR2016 battery provides roughly five years of operation, reducing maintenance demands compared with rechargeable alternatives. The LED backlight with afterglow supports low-light reading, while world time, daily alarms, and full auto-calendar functions cover routine scheduling. Mineral glass protects the dial face from scratches during normal use.

 

• Battery: CR2016, approximately 5-year life.
• Backlight: LED with afterglow for low-light visibility.
• Calendar: Full auto-calendar programmed to the year 2099.

 

5. Oversized Case Architecture and Wrist Fit

At 55 x 51.2 x 16.9 mm and 70 g, the GA100 is deliberately large, giving the dial room to display analog hands, LCD windows, and pusher functions without crowding. The resin band spans 145 to 215 mm, and the four steel pushers are shaped for grip with gloves or wet hands. This makes the watch a practical fit for field work, gym sessions, and outdoor activity where quick button access matters.

 

• Case Dimensions: 55 x 51.2 x 16.9 mm.
• Weight: 70 g, balanced for a large resin case.
• Band Range: 145 to 215 mm compatible band size.

 

The G-Shock X-Large GA100 is best suited for users who prefer a large, shock-resistant analog-digital watch with long battery life and 200-metre water resistance for training, field work, and everyday wear. For those who need quick stopwatch timing, a speed indicator, and a dial that stays legible without a recharge routine, the GA100 offers a rugged, low-maintenance option in an oversized format. It fits users who value impact protection and simple operation over smartwatch connectivity.
