TimexMen's Easy Reader Watch

My husband just had cataract surgery so cannot see his watch at night. now that he is far sighted, could he read this watch at night?

Which part lights up? The hands or the numbers?

I give up. How can i set the day of the month on my new t2h281 easy reader? Timex gives no readable instructions in box or on internet.

What type of battery does this watch use?
