The Casio G-Shock GMA-P2100SG-1ADR redefines compact toughness with its signature octagonal bezel design, scaled down to a slimline 40.2mm profile that suits smaller wrists without sacrificing the legendary shock resistance G-Shock is renowned for. This analog-digital hybrid pairs a striking gold-toned dial and hands with a robust matte black bio-based resin case and bracelet, creating a sophisticated contrast that transitions effortlessly from urban exploration to outdoor adventure. The dual-display format combines the intuitive readability of traditional hands with a digital sub-window displaying date, day, and additional timekeeping functions, offering both classic aesthetics and modern utility in a single instrument.
Engineered for reliability, this model features Casio's quartz movement with approximately 3 years of battery life, alongside practical complications including world time across 31 time zones, a 1/100-second stopwatch, countdown timer, and five daily alarms with hourly time signal. The Super Illuminator LED backlight ensures legibility in low-light conditions, while 200-metre water resistance provides confidence for swimming, snorkelling, and water sports. As an authorised retailer, Casio & Co. guarantees the authenticity of every timepiece, backed by Casio's international 1-year warranty and our commitment to after-sales support.
The GMA-P2100SG represents Casio's commitment to sustainability, incorporating bio-based resin materials derived from renewable organic resources in both the case and strap construction. This environmentally conscious approach maintains the full shock-resistant structure and durability expected from the G-Shock lineage, while the slim 11.2mm case height and lightweight 40g construction ensure all-day comfort. The octagonal case profile—a direct homage to the original GA-2100 'CasiOak' design—delivers a contemporary silhouette that has become an icon in modern watch design, equally at home paired with tailored attire or technical sportswear.

FAQ
Q: What is the difference between the GMA-P2100 and the GA-2100 series?
A: The GMA-P2100 series is a smaller, more compact version of the popular GA-2100 'CasiOak' line. With a 40.2mm case diameter compared to the GA-2100's 45.4mm, the GMA-P2100 is specifically designed to suit smaller wrists while maintaining the same octagonal case design and full G-Shock shock resistance. The GMA series also incorporates bio-based resin materials as part of Casio's sustainability initiative.
Q: Is this watch suitable for swimming and water sports?
A: Yes, absolutely. With 200-metre water resistance, this G-Shock is fully suitable for swimming, snorkelling, recreational diving, and various water sports. The screw-down case back and resin construction ensure reliable water protection. However, avoid operating the buttons underwater and ensure the watch is rinsed with fresh water after exposure to saltwater or chlorinated pools.
Q: How do I change between analog time and world time zones?
A: The GMA-P2100SG displays analog time continuously on the main hands. To access world time, press the mode button to cycle through functions until you reach the world time mode, where the digital display will show the time in your selected secondary time zone. The watch stores 31 time zones covering 48 major cities, and you can toggle daylight saving time on or off for each zone. Detailed instructions are included in the user manual provided with your purchase.
Q: What does bio-based resin mean, and is it as durable as regular resin?
A: Bio-based resin is derived from renewable organic materials such as castor oil and corn, rather than petroleum-based sources. Casio's bio-based resin maintains the exact same shock resistance, durability, and structural integrity as traditional resin materials used in G-Shock watches. This sustainable material choice reduces environmental impact without compromising the legendary toughness G-Shock is known for.
Q: How long will the battery last, and can it be replaced at Cassims & Co.?
A: The CR1025 battery provides approximately 3 years of operation under normal use. When replacement is needed, our watch servicing and repairs team at Mall of the South can replace the battery for you, ensuring proper sealing and water resistance are maintained. We recommend having the battery replaced by authorised service centres to preserve your warranty coverage.
Q: Can the resin strap be adjusted or replaced?
A: The resin strap is designed with multiple adjustment holes to accommodate a wide range of wrist sizes. If you require strap adjustments or a replacement strap in the future, visit us at our Mall of the South boutique where our team can assist with fitting and sourcing genuine Casio replacement straps. We stock a selection of G-Shock accessories and can order specific parts as needed.
Q: Does this model have a stopwatch function, and what is its accuracy?
A: Yes, the GMA-P2100SG features a 1/100-second stopwatch with a 24-hour measuring capacity. This allows you to time events with precision down to hundredths of a second, with split time and elapsed time functions. The stopwatch is accessed via the mode button and controlled using the dedicated function buttons on the case side.
Warranty
- Warranty Period: This Casio G-Shock watch is covered by a 1-year international manufacturer's warranty from the date of purchase.
- Warranty Coverage: The warranty covers defects in materials and workmanship under normal use conditions, including movement malfunctions, case or crystal defects, and manufacturing flaws.
- What Is Not Covered: The warranty does not cover normal wear and tear, battery depletion or replacement, strap or bracelet wear, scratches or cosmetic damage to the case or crystal, damage caused by accidents, misuse, improper handling, unauthorised repairs or modifications, or water damage resulting from improper use or failure to observe water resistance limitations.
- Authorised Retailer Requirement: This warranty is valid only when the watch is purchased from an authorised Casio retailer such as Cassims & Co. Proof of purchase from an authorised dealer is required for all warranty claims.
- Water Resistance Note: Water resistance is not a permanent condition and may diminish over time due to aging of gaskets, accidental impact, or improper use. Water resistance must be maintained through periodic inspection and gasket replacement, which are not covered under warranty as they constitute regular maintenance.
- Warranty Service: For warranty service, contact Cassims & Co. with your proof of purchase. We will coordinate with Casio's authorised service centres to assess and repair your watch under warranty terms. Transit to and from service centres may be subject to additional handling procedures.
- After-Sales Support: Beyond warranty coverage, Cassims & Co. provides ongoing support for battery replacements, strap adjustments, and general maintenance for all Casio watches purchased from our store. Visit us at our Mall of the South boutique for assistance.
Care Guide
- Regular Cleaning: Wipe the watch case, crystal, and resin strap regularly with a soft, lint-free cloth to remove dirt, sweat, and oils. For deeper cleaning, use lukewarm water and mild soap, then rinse thoroughly and dry completely.
- After Saltwater Exposure: Always rinse the watch with fresh water after exposure to seawater or chlorinated pool water, as salt and chemicals can degrade the resin over time. Pay particular attention to the strap, case back, and button areas.
- Avoid Chemicals: Keep the watch away from solvents, detergents, perfumes, cosmetics, and harsh cleaning agents, as these can damage the resin material, cause discolouration, or compromise water resistance seals.
- Button Operation: Do not operate the buttons when the watch is wet or underwater, as this can allow water to enter the case. Ensure buttons are not pressed continuously or with excessive force.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (below -10°C or above 60°C) for extended periods, as this can affect battery performance, resin flexibility, and timekeeping accuracy.
- Impact Protection: While G-Shock watches are designed to withstand shocks, avoid subjecting the watch to extreme impacts such as dropping from significant heights onto hard surfaces, or striking the crystal directly against hard objects.
- Storage: When not wearing the watch, store it in a cool, dry place away from direct sunlight, magnetic fields, and electronic devices. Avoid storing in humid environments such as bathrooms.
- Battery Replacement: When the digital display becomes dim or functions become sluggish, have the battery replaced promptly by an authorised service centre to prevent potential leakage that could damage internal components.
- Water Resistance Maintenance: Have the water resistance gaskets inspected during battery replacement. While this watch is rated to 200 metres, seals can degrade over time and should be checked every 2-3 years or after battery changes.
- Professional Servicing: For any technical issues, timing irregularities, or physical damage, consult our watch servicing and repairs team rather than attempting repairs yourself, as this could void your warranty.
