Casio Edifice – ECB-10DB-1A9DF

“Smartphone Link | A smartphone link model featuring an octagonal bezel from EDIFICE, which continues to evolve as an advanced high-performance metal chronograph.
As long as the watch is close to a smartphone, it can link to the dedicated “”CASIO WATCHES”” app through Smartphone Link via Bluetooth®, and connect without button operations to correct the time. Functions like the schedule timer, which notifies wearers when events scheduled on smartphones begin and end, are also very convenient.”
