OrientMen's Japanese Automatic/Hand Winding 200 M Diver Style Watch RA-AA08

Is the date wheel in Japanese?

Does it have a screw down crown?

Are the links on the bracelet screw links or push pin links? If they're screw links, what size screwdriver would I need to adjust the bracelet size?

What size replacement band (mm) is needed to change the bracelet on this watch?
