The Reflex Active Sea Venture 400R represents a significant evolution in fitness-oriented smartwatch design, combining robust outdoor credentials with genuine swim-safe engineering. This AMOLED-equipped timepiece is built around a 1.43-inch ultra-high-definition always-on display, delivering exceptional legibility in all lighting conditions without requiring wrist gestures or touch activation. The black dial features bold white Arabic numerals at 12, 3, 6, and 9 o'clock positions, with three sub-dial displays tracking heart rate, activity metrics, and world time—the latter reflecting the integrated dual-time functionality ideal for travellers and global professionals.

Water resistance is certified to 5ATM (50 metres), making this smartwatch suitable for pool and sea swimming—a genuine rarity in the category. The grey silicone strap is textured for enhanced grip and comfort during intensive training, while the stainless steel bezel with tachymeter-style markings adds visual depth and sporting character. Integrated GPS enables accurate route tracking without reliance on a paired smartphone, and Bluetooth calling functionality allows you to manage communications directly from your wrist. At Cassim & Co., we recognise the Sea Venture 400R as an exceptional value proposition for athletes, outdoor enthusiasts, and anyone seeking comprehensive health monitoring in a genuinely water-resistant package.

The watch tracks over 100 sport modes, monitors sleep quality, heart rate variability, and blood oxygen saturation (SpO2), and offers customisable watch faces to suit your mood or occasion. Battery life extends to several days under typical use, and the magnetic charging cable ensures effortless power top-ups. For those seeking a feature-rich smartwatch that doesn't compromise on water resistance or display quality, browse our full range of REFLEX ACTIVE watches to explore the broader Sea Venture and Series 18 collections.

Care Guide
  • Rinse the watch and silicone strap with fresh water after exposure to saltwater, chlorine, sweat, or other contaminants to prevent residue build-up.
  • Dry the watch thoroughly with a soft, lint-free cloth after rinsing, paying particular attention to the charging contacts on the rear case.
  • Avoid exposing the watch to extreme temperatures, saunas, hot tubs, or thermal shocks, as these may compromise the seals and internal components.
