Smartphone Link | Super Slim High Spec Chronograph | Solar powered | Despite being a high-spec multi-hand chronograph with a smartphone link via Bluetooth® and being equipped with Tough Solar, which charges even in low light, this model achieves both high functionality and wearability via a thin 8.9 mm case. It enables functions such as world time, which controls and corrects time via a dedicated smartphone app that is able to select times for approximately 300 cities, and a special stopwatch function that comes in handy while watching races. The EQB-1100X series uses a tachometer mounted on an octagonal bezel. This gives models in this series a sportier design. A scratch-resistant sapphire crystal with an anti-reflective coating ensures high visibility. The bezel is green ion plated and the case and band are black ion plated to make them scratch resistant.
