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.

this is the perfect daily everyday use digital watch........
Color: Black
hands down the best edc digital watch available, this watch is everything you need at a quarter of the cost of other digital watches. we all know the durability of iron man watches its legendary, but where this watch beats even other iron man offerings is the size of the digital numbers displayed a bit larger for aging eyes and what makes it even more durable than the other iron man watch's is that the instructional labeling of the buttons is under the glass and wont fade or rub off under use making it look cleaner and newer for longer. now lets mention the size or foot print of this watch, i own several watches from competing brands and almost once a day i hit the watch on something a door knob a table corner, but when I'm wearing this Timex 40mm i never hit it on anything due to the thinness of the watch.
