Built for daily knocks

The Casio G-Shock GA-100FL-1A is a men's sports watch with a 51.20 mm resin case and matching resin strap. Quartz movement drives an analog digital display on a blue dial with index markers. A mineral crystal protects the face and the construction is shock resistant.

Suits outdoor and active wear

This watch fits users who want a single tough timepiece for swimming, training or shift work. The 200 m water resistance and fixed bezel handle regular immersion. Buyers who need a slimmer profile, a metal bracelet or smartwatch connectivity should look at something else.

Consistent under pressure

The quartz movement keeps steady time during prolonged vibration or temperature swings. The mineral crystal resists scratches from repeated contact with gear or surfaces. Water resistance holds at depth for extended sessions, not just brief splashes.

Questions about this item

Does the watch need any external power source or charging cable to operate?

The quartz movement runs on an internal battery that is already fitted, so no external power source or charging cable is required for it to work.

Will the 51.20 mm resin case fit comfortably under the cuff of a standard dress shirt?

At 51.20 mm thick the case sits proud of the wrist, so it will likely catch on a close-fitting shirt cuff; looser or rolled cuffs work better.

How can I confirm the 200 m water resistance is still effective after I start wearing it?

Have the seals pressure-tested by a watchmaker once a year or after any hard impact; a passed test confirms the 200 m rating remains intact.
