The Reflex Active Series 23 Nexus 100 S smartwatch merges contemporary square-case design with serious fitness functionality, housed in a durable blue silicone case and strap combination that stands up to the rigours of daily training. Its 1.83-inch AMOLED display delivers brilliant clarity for quick glance-and-go readability during workouts, while the intuitive interface keeps health metrics, notifications, and workout data instantly accessible. This blue-cased smartwatch is engineered for those who track their performance seriously—heart rate monitoring, blood oxygen measurement, sleep analysis, and multiple sports modes transform raw effort into actionable insight, all synced via Bluetooth connectivity to your smartphone.

GPS connection enables accurate route and distance tracking for outdoor runs and rides, while music control functionality means you can adjust your playlist without breaking stride. The day-date complication and battery indicator ensure you stay informed at a glance, and the watch's wellness features—including step counting and calorie tracking—integrate seamlessly into your daily routine. Whether you're logging laps at the gym or simply navigating a busy workday, the square case profile and bold blue silicone strap make a distinctive statement on the wrist, blending athletic capability with modern styling.

FAQ

Q: How do I sync the Reflex Active Nexus 100 S with my smartphone?

A: Download the Reflex Active companion app from the App Store or Google Play, enable Bluetooth on your phone, and follow the in-app pairing instructions. The watch will sync your health data, notifications, and settings automatically once connected.

Q: Does this smartwatch have built-in GPS?

A: The Nexus 100 S features connected GPS, meaning it uses your smartphone's GPS signal to track routes and distances during outdoor activities. Keep your phone nearby during runs or rides for accurate location tracking.

Q: How long does the battery last on a full charge?

A: Battery life depends on usage patterns—frequent GPS use, heart rate monitoring, and notifications will drain the battery faster than basic timekeeping. Typical usage yields several days between charges; refer to the user manual for detailed estimates and charging instructions.

Q: Can I control music playback from the watch?

A: Yes, the Nexus 100 S includes music control functionality. Once paired with your smartphone, you can play, pause, skip tracks, and adjust volume directly from the watch interface without reaching for your phone.

Q: What health metrics does this smartwatch track?

A: The watch monitors heart rate continuously, measures blood oxygen levels (SpO2), tracks daily steps and calories burned, analyses sleep patterns, and logs workouts across multiple sports modes. All data syncs to the app for long-term trend analysis.

Q: Is the Reflex Active Nexus 100 S suitable for swimming?

A: The watch offers splash resistance for everyday wear and handwashing, but it is not rated for swimming or submersion. Avoid exposing it to prolonged water contact, showers, or aquatic sports to prevent damage.

Q: Can I replace the silicone strap if it wears out?

A: Contact our team at Cassims & Co. for guidance on strap replacement options and compatibility. We're here to help keep your smartwatch looking and performing at its best.

Warranty
  • This smartwatch is covered by a 1-year Reflex Active manufacturer warranty from the date of purchase, valid when bought from an authorised retailer such as Cassims & Co.
  • The warranty covers defects in materials and workmanship under normal use conditions.
  • It does not cover damage caused by accidents, misuse, water ingress due to improper handling, unauthorised repairs, or normal wear and tear including strap degradation and screen scratches.
  • Battery performance degradation over time is considered normal wear and is not covered under warranty.
  • To claim warranty service, retain your original proof of purchase and contact Cassims & Co. for assistance—we will facilitate the process with Reflex Active on your behalf.
  • Warranty service may include repair or replacement at the manufacturer's discretion.
Care Guide
  • Wipe the case and strap regularly with a soft, lint-free cloth slightly dampened with water to remove sweat, dust, and oils.
  • Avoid exposing the smartwatch to harsh chemicals, solvents, perfumes, or cleaning agents that may degrade the silicone or damage the AMOLED display.
  • Do not submerge the watch or wear it in the shower, pool, or during water sports—splash resistance is not the same as waterproofing.
  • Remove the watch before engaging in high-impact contact sports or activities that could subject it to heavy shocks or scratches.
  • Charge the device using only the supplied charging cable and a reputable USB power source; avoid cheap third-party chargers that may damage the battery.
  • Store the smartwatch in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
  • Update the firmware regularly via the companion app to ensure optimal performance, bug fixes, and new feature releases.
  • If the strap becomes loose or damaged, contact Cassims & Co. for replacement advice to maintain secure wrist fit and comfort.
