This material protects the internal module from shock-induced damage. The dual back cover protects the back surface against impact. The case provides a comfortable fit, even though the watch is designed with a wide face. Equipped with Smartphone Linking for ease of setting approximately 300 world time cities, alarms, timer, time swapping, phone finder, and hand alignment correction. The watch comes with a stainless steel link bracelet that secures in place with a buckle clasp and is water-resistant to 200m.
