A waste
Color: White/Silver-Tone/Digital
If I could I would give it zero stars. It was running when I received it so who knows how long the battery has left. No instructions were included. The setup is impossible unless you’re into computerized “smart” crap. I looked up how to do that and it’s way too involved for a watch to tell me what the time is. I don’t want a personal dictator, I just wanted a watch I could wear and know what time it is. Too much hassle to return. It’s going in the trash. Total waste of time energy and money. Zero stars.

Favorite Watch
Color: Black/Silver-Tone/Digital, Color: Black/Silver-Tone/Digital
I have been using this same kind of watch for 10+ years. I like the belt like strap and the small size. I also appreciate how it has a light on it, the date, and the stop watch. I haven’t had any issues with the battery. These watches have held up well for me although I try to avoid getting them wet. The buttons are hard to press when you first get them but get a little easier to press over time. I still have issues remembering how to change the time and typically have to look up how. The silver parts on the front do wear out over time and turn copper colored. I wore one of these watches for around 5 years before buying a new one when the band which holds the excess space from the band broke. Attached is a picture of the watch that I wore for at least 5 years and a brand new one that I bought.

hard to read display, no manual included.
Color: Black/Black/Digital
I haven't decided yet whether or not I will keep the watch. Problem is there is no instruction manual attached and you cannot find one online. However if you call Timex support they will email you the manual if you give them the model number which is included in Amazon's product description. However even with the manual watch is very hard to set. It lacks some functions normally Timex has like time can only be set up there is no down button. And most importantly display is minuscule. So it is really hard to read to set. Watch is a ladies watch. It is small and I like it a lot. But buttons are hard to operate and it is hard to read.
