CasioVintage LA680WGA-1BDF Black Digital Dial Gold Stainless Steel Band D205

Does this have an hourly time signal?

Anyone taken this into water or swimming?

In the pics the display looks rather dark. Is it bright enough w/o using the light button (waht is that?) that a pair of 80 year old eyes can see it?

Is this watch adjustable? I have a 6.5" sized wrist.
