Its lightweight construction and smaller profile make it especially suitable for teens and adults wanting a versatile everyday G-SHOCK with a softer, fashion-focused look.

 Constructed using bio-based resin made from renewable organic resources, the watch combines lightweight comfort with durable everyday performance while helping reduce environmental impact. Casio’s Carbon Core Guard Structure enhances strength and impact resistance while keeping the watch slim and wearable throughout the day.

Built with G-SHOCK shock-resistant construction and 200-metre water resistance, the GMA-P2100-4A is suitable for swimming, travel, sport, and active daily wear.
