Casio has introduced three G-Shock GMA-S140 watches in Japan, featuring metallic pink gold detailing. The collection includes the GMA-S140PG-1A with black resin, the GMA-S140PG-4A in light pink, and the GMA-S140PG-7A in white. Each model displays a metallic pink gold dial with rose gold backgrounds on digital inserts.

The hybrid analog-digital design measures 49.0 × 45.9 × 15.8 mm and weighs 56 grams. Casio uses bio-based resin from renewable organic resources for the case, bezel, and band to reduce environmental impact. The watches are shock-resistant, magnetic-resistant, and water-resistant to 200 meters, with mineral glass protection.
A CR1220 battery powers the watch for approximately two years. Accuracy is ±15 seconds monthly. The analog section features hour and minute hands, with the minute hand advancing every 20 seconds. Digital displays show time, date, and day information.



World time covers 29 time zones across 48 cities plus UTC, with daylight saving adjustments. The stopwatch measures in 1/1000-second increments up to 99:59’59.999”, tracking elapsed, lap, and split times. Speed measurement ranges from 0 to 1998 units per hour, with distance input from 0.0 to 99.9 and a Mach indicator above 1225 units per hour.
The countdown timer operates in one-second units up to 24 hours, with start times adjustable from one minute to 24 hours. Five daily alarms include one snooze option, plus an hourly time signal. An amber LED provides illumination with auto-switch, selectable 1.5 or 3-second duration, and afterglow. Compatible band sizes range from 135 to 200 mm.
Pricing & availability
The watches retail for ¥18,150 ($116) in Japan. Casio’s international website listings indicate potential expansion to the United States, United Kingdom, and Germany.
