Casio GMAS-110ST-7A G-Shock S-Series Analog-Digital White Resin Band

Casio GMAS-110ST-7A: G-Shock DNA in a Compact Package

Not everyone wants a 51mm watch strapped to their wrist. The G-Shock S-Series addresses that with the same 110-series design language scaled to 45.9mm. The GMAS-110ST-7A goes further with a pearlescent white finish that Casio describes as “silk-like”—it shifts between cool white and warm cream depending on the light.

Size Without Sacrifice

At 45.9mm and 56 grams, this wears noticeably smaller than its full-size siblings. But it’s still shock-resistant, still magnetic-resistant, and still rated to 200 meters. The bio-based resin case and band get the same engineering as the big G-Shocks—just in a more approachable package.

The Details

Rose gold accents on the dial and hands add warmth to the white case. The analog hands sit over dual digital displays showing day, date, and secondary time zone. All the standard G-Shock features are here: world time, stopwatch with lap memory, countdown timer, five alarms. The LED backlight glows amber for night visibility.

Who It’s For

If you’ve avoided G-Shock because the standard sizes felt too bulky, this is worth a look. The 45.9mm case works on smaller wrists without losing the recognizable 110 silhouette. The pearlescent finish is more interesting than standard white—it’s subtle until the light catches it.
