Timex quality and reliability 👍🏼👍🏼
A really nice watch with a face big enough to easily see the numbers. One thing I like is the watch band is more comfortable than usual ones. Recommended

Another great Timex
Another great Timex. The large numerals are very easy to read and yet don’t overwhelm the face. It has a really nice lume along with Indiglo so I can see the time even in complete darkness. It has a fun feel to it while still looking classy. Well done, Timex.
