the watch does a good job to display all the info I need at a glance, time, day, and date. No problems holding up to heavy wear and cleans easily. The controls are somewhat confusing but I can make it work with a bit of trial and error. After 2 years with mine the band broke and I bought a replacement watch since I'm so used to this one and they're cheap as dirt.

Better Than I Hoped

Color: blue, Color: blue

I have had Apple Watches for the past 6 or so years. I wanted to try out a basic watch again. I looked at digital watches but some were still over $100. I thought I’d give this watch a try as the price made it a pretty low risk. No notes. It looks great and does what watches are supposed to do. I wish it had a vibrate so I could use it as an alarm clock without waking up my wife.
