Nice Watch... But Buyer Beware!
Color: Black/Black/Black, Color: Black/Black/Black
This is a great looking and very functional watch for the price, so I was very disappointed to find it didn't work properly. Close examination revealed a tiny plastic collar preventing the crown from being fully depressed as necessary. I'm aware most new watches come with a small plastic tab that must be removed to activate the watch: this was not that. Those tabs are designed to be easily removed with one's fingertips. This collar (shown in the photo) was barely accessible due to the crown, and could not be removed even with fine-tipped watch repair tools.
I contacted Timex customer support and sent them the photo. They evaded my question as to what the collar was and why it was there, but confirmed it needed to be removed for the watch to function, suggesting I bring it to a jeweler/watch repair shop. Well, the watch isn't such a bargain anymore if I've got to pay someone to get it to work -- so I returned it and requested a replacement.
Wouldn't you know it? The replacement had the same stupid plastic collar preventing it from working. This time I decided to see if I could fix it myself. I removed the case back with a pry knife, removed the plastic battery cover, used a pin-punch to release the watch stem, and fully removed the stem from the case, finally freeing the offending plastic collar. Pretty straightforward if you have the tools.
Reassembly was trickier, as two miniscule push bars fell out when the plastic battery cover was removed. These allow the chronograph pushbuttons to activate the stopwatch. They're smaller than a grain of rice and sit loosely within tiny channels in the battery cover, so they are very prone to falling out as the cover is put back in place. It took several attempts to get the battery cover situated with them still seated. Then it was just a matter of carefully placing the watch in a case press to snap the case back in place.
Once reassembled, the watch worked fine. I replaced the rubber strap with a NATO strap, and it's now a favorite daily beater watch. I'm astounded no other reviewers seem to have encountered this issue when I encountered it TWICE, but I've detailed it here in case others run into the same problem. Disassembling the watch to remove the troublesome plastic collar isn't that big a deal if you have watch repair tools and steady hands -- but if that's not you, you might have to decide whether it's worth paying a jeweler to repair your brand new watch.

Highly recommended for a first-time buyer!
Color: Black/Black/Black
As a newcomer to the world of watch collecting, I wanted my first serious piece to be something reliable, functional, and stylish. After spending some time with the Timex Expedition Field Chronograph, I can safely say it exceeded my expectations.
Design and Build Quality
The first thing that caught my eye was the color palette. The earthy, rugged tones give it a great "field watch" look that works for both daily wear and outdoor adventures. Despite its 43mm size, the weight feels substantial without being overbearing. The finish is impressive for this price point; it feels incredibly durable and well-built, like it can actually handle the "Expedition" name.
Readability and Function
I was initially a bit worried that the chronograph sub-dials might make the face look cluttered, but I found it surprisingly easy to read. Once you get used to the layout, tracking the time at a glance is a breeze.
The "Killer Feature": INDIGLO
The standout feature is definitely the INDIGLO backlight. It is, quite simply, excellent. It makes reading the time in low-light or total darkness effortless. It’s one of those features you don’t realize how much you need until you have it.
Final Verdict
For anyone just starting their collection, this watch offers a perfect blend of style and utility. It feels like a tool that is built to last, and I’m really happy with how it looks on the wrist. Highly recommended for a first-time buyer!

Uncompromising Quality at Every Price Point
I really like this watch. The case and back are made of steel and it is substantial. The glass is very hard and clear. The writing on the face is subtly three dimensional (it’s not just printed on the surface). Even the three circles on the face have very precise, slightly raised concentric circles.
It’s a little hard to see the black hour and minute hand agains the military green watch face in low light. But it is also what makes this watch aesthetically unique. I am a little confused as to why the second hand is bright yellow, but the hour and minute hand are not outlined in yellow. If you are in sunlight, it’s easy to read the time.
I got the version with the rubber band. I like that a lot too. Soft, substantial, pliable. Very comfortable.
Timex is consistently high quality for each price point (ranging from $20 resin cases to $2,000 titanium). If you pay more, the materials and details match that price. But, the quality is always uncompromising. And their watches are both simple and aesthetically pleasing.

Great watch, but serious design flaw; Not expedition worthy.
Color: Black/Black/Brown
This is a great watch. Love the metal casing, band, and aesthetic design. Although it looks and 'feels' rugged, it is not worthy for the man of adventure. Let me explain.
The middle knob of the watch (the main knob that you push for light/pull to set time) is a bit large and too exposed for its own good. This makes the knob vulnerable to any stress. Example, if you flex your wrist/hand backwards throughout your adventures, whether pushing yourself off the ground or climbing over rocks, the back of your hand places pressure on the knob. The knob eventually reacts to this stress by breaking off. The knob has a little metal stem behind it that appears to be made of lower quality metal. This knob is crucial to the watch as it is used to set the time (by pulling and turning knob). Without it, the watch is useless regarding time.
If you are having difficulty understanding the hand/wrist stress, think of yourself in a push-up position while wearing the watch. The back of your hand places stress on the knob which is exacerbated by the angle of the watch strapped in that position.
Perhaps I had a fluke, but this same problem happened on 3 watches. Yes, I loved this watch so much, that I purchased it 2 more times. The knob on the first one broke after being in the field doing archaeology, the second in an outdoor adventure, and the 3rd occurred by simply pushing myself off the floor after lying down. The knob broke off in all 3. This is a design flaw combined with low quality metal for the metallic rod behind the knob.
If you look at a few other Timex 'expedition' models, you'll see the case is molded to the sides of the knob, protecting it from stress. This particular model could use something like that. I really loved this watch and still do. But I cannot recommend it to men who do active things. If you have a simple life working in the office and come home to the couch, this watch will suit you fine. For all others who move their hands in all sorts of directions, beware of this watch.

Great starter Field Watch. Rugged but simple and elegant.
Color: Black/Black/Brown, Color: Black/Black/Brown
I've been wanting to own a field watch for a while. I never got used to smart watches anyway, so I decided to go for a good brand that doesn't cost too much. I decided for this Time Expedition because it gas a good balance between rugged looks, simplicity and elegance. It's perfect for wearing every day, but also great for when you need to dress up as well.
If you are planning on getting this watch, be aware that the seconds are tracked on the small dial at the bottom. The large "seconds" hand it's meant for the chonograph feature, so it will sit static at the zero mark until you start the chonograph.
You also need to set it up out of the box. It's a simple process to set up the time, the date and reset the small dials in the zero position. The watch came without a manual, but there are plenty of videos on Youtube showing how to set up and use this exact model
The band is simple but elegant. It looks like nobuck but it's not really real leather. I can't say how durable it is yet or how long it will look over the time, but Timex is respectable enough so I expect this band to last several months. It can be replaced and there are lots of aftermarket options so I don't worry about this.
As other Expedition watches, it also comes with the Indiglo feature. You can activate night mode by pushing down the main button, then the entire face lights up. When using this feature, I noticed that the hands (being white) do not have a good contrast against the lit up face, but you get used to it. The hands themselves are bright under low-light conditions, so you don't really need the Indiglo feature unless you need to see other details from the watch
Anyway, I'm very happy with this purchase.
