Thank you for viewing! This is an offering for the ECB-900YDB-1BJF from Casio's Edifice series. This is a genuine domestic model, so the crystal is sapphire glass. The parallel model of the same type (ECB-900DB-1JF) uses mineral glass for the crystal, making this model a much better deal. It has been used daily, so there are some minor scratches. There are light scratches on the bezel and band, but the glass surface has no noticeable scratches. The wrist size is 17cm, but 4 extra links are included, allowing for adjustment up to approximately 20cm. Other accessories include the dedicated box. It has a sporty design with a black base and blue accent colors. It is a multi-functional model that displays various information clearly on the LCD in addition to the hands. By linking with a smartphone via Bluetooth, it displays the exact time to the second and has a world time function that allows you to easily select a city from approximately 300 cities. Other features include solar charging, automatic time correction, speed indicator, lap time measurement, and auto light. You can even use the watch to find your registered smartphone.
