Timex should be ashamed
Color: Black/White/Silver-Tone
Bought this for my wife because she likes my Timex Weekender, but the 38mm is to large for her. I’m incredibly disappointed in the quality on hers. - the crown/stem is incredibly hard to pull out due to the lack of any lubrication on the setting lever or clutch wheel. You can feel it when pulling the crown to set the time, that is if you can even pull it out. It’s stuck in the watch and you have to pull with such force it will break the crown off or the stems internal components will wear prematurely. - the seconds hand doesn’t hit the markers which honestly is not a huge deal on a watch this price. It’s hit or miss for watches of any brand in this price range. - the hour hand is misaligned. This is a issue and not acceptable no matter the price of the watch, especially for Timex. I’m not happy at all and quite disappointed. Timex should be ashamed to sell a watch leaving the factory like this.

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.
