Infantry 5ATM Waterproof Mens Military Tactical Field Watch, Date & Day 12/24Hr-
Color: Silver
So I almost never write reviews- anywhere. This is an exception & I'm not paid or reimbursed- just impressed. This watch presents a really good price to value ratio. My infantry watch looks great and is very functional. I put a NATO strap on it because I tend to be tough with watches, though the one it arrived with is very nice looking and the buckle is even logo'd- a really nice touch in this price segment. I've received several positive compliments while wearing it and 1 of my friends has purchased an Infantry field watch from this same series since. The company behind the watch is part of the value equation. I had a minor issue and I was able to get in touch with a real person... no, actually two! I contacted via Amazon AND through the support dept from their website. Both inquiries were promptly answered with a helpful and well-mannered reply and the perfect solution. There are several collections to be found on their website (SEARCH: Infantry Watches ). These watches range in appointment and quality from levels found here to several steps above. Similar in looks and nature to this one on Amazon include; The Chronomaster, The Skeleton, and The Auto-Pilot to name a few. I've begun to add additional watches to my collection from those. There are also fun and informal collaborations offered. Right now [8-2025] these include; Transformers, Monopoly, Peanuts and several others. ---> Overall it's rare and refreshing to find a company still able to work decent products AND ethics into a successful business model!

Simple, affordable, smartly styled. Good starter watch for teens
Color: Black
Got this for 13-year-old boy for Christmas. Excellent choice for a beginner's watch. Learn to read a clock face for crying out loud! Easy to set the day/date, and has a comfortable band.

Style classic
Color: Silver
A neat watch, I was a career soldier and I remember getting a few different military style watches, mostly made by Timex. I was in supply so had access to them, often the style was the same and sometimes not. Item was packed well and arrived fast great price

Decent watch for the price - you get what you pay for
Color: Black
This watch is about what I expected for the price. It's comfortable to wear and is keeping time reasonably well thus far. Illumination on the hands and dial fades after a couple of hours and setting the day of the week does not work (it will not advance - day just sort of "bounces" in the window - although the day changes on its own). Given the reviews I read, I take it off before showering and avoid getting it wet when washing my hands, as I don't trust the water resistance. EDIT: After posting the generally positive review above, the seller messaged me offering a replacement on their own initiative and allowing me to keep the original watch. I did not expect that but accepted their offer. Upon receiving the replacement, I discovered that the problem setting the day of the week was user error and not a problem with the 1st watch. My only criticism of the watch remains that the illumination fades within an hour or two (I held it next to a 150W lamp bulb for 30 seconds) but I am willing to live with that and believe the watch is a good value. I increased my rating from 3-stars to 5-stars on the strength of the great customer support and what I think is the value proposition for a very comfortable, easy to read, $20 watch. I would buy again.
