The watch of our era
Color: Blackout
Bought this ‘used’ but looks like only the box had some ‘damage’ but the watch was perfectly brand new. I’ve been wearing a timex Ironman watch since my tenth birthday. I’ve served in the Marine corps and wore one while on tour. I’ve worn them snorkeling and diving. I’m a mechanic and have worn it on my belt loop while working, and depending what I’m doing I’ll leave it on. I wear it in the shower, the pool, beach, kayaking, skydiving, mudding, surfing, fishing, shooting, and while relaxing in my recliner. I’ve only had one battery die, and it was easily replaced. This is the watch of our era. Stop reading this review and buy one!

Very dim
Color: Black/Yellow Accent
This was a gift for our son. The watch functions well, but I returned it because the screen was very hard to read.

Trust this seller speaks the truth!!
Color: C-Blue
Comfort is a 10! Appearance is very very nice!! Readability is excellent! Accuracy is 💯 !! Quality is a 10! Value - couldn’t love it more!! At first I didn’t think that he sent me a watch without a battery, but lo and behold I opened the box again and definitely saw the watch was working! I’ve been scammed several times- but this is truly AWESOME !!! Thank you all!!!

Hard to set day/date.
Color: A-Black
Watch very professional looking and appears to be well made. Everything about this watch is what I have been looking for at a reasonable price. The only issue I have is how to set the watches features, time, date, and day. The instructions are very clear and well written, to a point. That point being the instructions say to move the "crystal" to the first notch, to adjust the day/date, and the second notch for to set the time. What the instructions fail to mention is the day/date adjustment must be turned a full 24 hours to the next day or date settlings. Also, trying to hit just the second notch is almost impossible as the is no distinct way of knowing if you are in it or not,
