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 boasts a thin 8.9 mm case to enhance wearability. Major features include the "Accurate Time System" that automatically links to a smartphone four times a day via Bluetooth® to correct the time, and world time that allows wearers to select cities from the approximately 300 cities on the smartphone app. The stopwatch, which has a 200-lap memory, transfers measurement data to a smartphone where it is recorded via the app in 1/1000 second units. It is also equipped with a last lap indicator, which displays the time difference between the last lap than the previous lap.
