I had one just like this before. Great watch except they made one very bad change in the band which makes them fall apart within weeks. They don't tell time if you have to throw them in the garbage because of bands that fell apart. I like it, a nice clean dial, works fine, and you can make it light up to check the time in the dark. But some idiot made a terrible design change in the band. The center 1/3" of band is not twistable and falls apart easily. I've had two of these; both fell apart within weeks. The previous similar one that I owned without this design defect lasted me many years.

its a simple watch

Color: Silver-tone/White

This was a gift for my 80 Y/O father, the numbers are easy to read and the date (Numbered day only) will have to be adjusted if the month is 30 days instead of 31. The wristband fit perfectly, so there was no adjustment of links. He has had it for a month now and forgot to take it off when he entered the shower, still works, but wont let that happen again. If it lasts a year I will be happy, it wasn't expensive for a Timex and the silver color looked like silver.

Time work watch

Color: Silver-tone/White

Inexpensive work watch, they last forever, the only complaint I have is that the band broke and I couldn’t find a replacement band, so I had it repaired instead , the watch works great.
