Sturdy & we repurchase yearly for Hubby’s refresh
Color: Brown (Rodeo)
This is my hubbys tried and true wallet. He requests this same one every year as a refresh. He wears his 24/7 in his back pocket so it gets discolored but still holds its shape pretty well with a slight bend.

My favorite watch of all time by a long shot
Color: Brown/Green/Tan, Color: Brown/Green/Tan
Hands down this is the best watch I've gotten so far. I love my Infantry watch but with 24mm bands it's a big sucker. Then there is my Timex Expedition Gallatian which comes in at 22-23mm which is just perfect for my size wrist. It's a perfect fit and I LOVE the Velcro "Fastwrap" strap that comes with it. It's sometimes so comfortable I forget I'm even wearing a watch and it still holds up when swimming! And now this guy, the Expedition Resin Combo as it's called. It at 20mm band size, it is a tad small on my wrist - I wish it was 22mm size as it'd be a 6star or 7star watch haha. Once I got the other Timex watch I knew this "Expedition" series would be awesome. However I didn't like two things about the first one, the date had to be set by continually winding clockwise till you got the day (very tedious) and the indiglo made it so you couldn't see the date. So I decided I want an analog/digital combo but in the Expedition series. On Amazon at least there were only 2-3 models of Timex Expedition that had this specific combination. So I opted for the shall we say middle of the road option for price vs elegance. So when the Expedition Resin Combo came in I was wowed by how amazing this thing is. It's got SO MUCH functionality it's not even funny. Digitally set your date, set your alarm (two diff alarm times), use a stopwatch function, and get both 12-24 hr digitally and analog, and has glow in the dark analog hands/light up digital indiglo feature, and is water resistant up to not 30, or 50, or even 75meters but up to 100 meters water resistant. Oh did I mention it has a rotatable divers bezel which rotates clockwise and counter? Yup got that too. This is by far the BEST watch I've owned period in terms of functionality. In terms of design it's also really stellar. I wish again it was a tad bigger but only by mm's. It came with a really nice brown traditional style wrist strap that was actually very comfortable, but for me is a no go as I'm slightly allergic to stainless steel when I wear watches, so I need to cover up the backplate and as nice as the stock strap is, it just didn't work for me. So I attached quick release pins, and the Velcro expedition strap which feels amazing. I also picked a really nice NATO style strap which again prevents direct skin contact at all times. THAT combination is equally as comfortable as the Velcro strap. The indiglo is some of the brightest I've seen, the analog hands will glow at even the slightest hint of charging in nearby ambient light. I know people talked about the crown or the dual dial that sets the analog hands being weak and breaking ( time will tell) but so far I've set it once and have forgotten about it as this thing does a great job of not losing time at all. If Timex came up with some sort of smart interface for the digital portion of the watch that'd be sick. But for now the 1980's calculator style numbering and lettering for the digital portion brings about a kind of retro feel. I also picked up a Voguestrap Velcro strap more along the colors of the watch but it wasn't long enough to fit around my wrist nicely without being too tight. Something to watch out for when buying a band/strap for the watch. All in all so far I givethis watch 5stars and I can't stop wearing it over my other watches including my Infantry brand watch which feels really comfortable with the NATO strap, but just isn't bright enough at night compared to this watch with the indiglo. I mean it's bright and it's awesome haha. Unlike my other Expedition watch it doesn't block the date or digital portion of the watch from being seen at night, you can see the entire face of the watch, period. And it's great. Would I buy this watch again should it break?? Absolutely. Would I buy this watch over other more expensive watches with better features? Yea absolutely. Let me tell you this is about the best watch you can buy without getting a smart watch or gps watch and keeping it outdoor elegant. I love the outdoors (hate spiders still) and can absolutely say this watch would serve me well no matter the circumstance, indoors outdoors daytime nighttime, wartime, sleeptime, in the rain, in the snow, in the desert, and in the arctic. This will undoubtedly be with me for a long time. And because it's so small I hardly notice it unless I wanna check the date or time. Stop looking and get this watch. You'll get over how small it is really quickly. If you don't, then hey scour for the two models I spoke about earlier, they might be more up your alley. This one is just about perfect for me.

The Coolest Timex Watch In Years
Color: Brown/Green/Tan
This is the nicest looking watch Timex has done in a long time. I have worn their Expedition watches before, usually my watch of choice for deployments, because they are basically indestructible. And if they do get scuffed or beat up, they do not cost a fortune to replace. I like the features of this particular watch. The rotating bezel is a major plus. The crystal is slightly recessed behind the bezel to protect it from scratches. And the watch is waterproof. The visibility of the dial and hands is excellent both in daylight and using the awesome Indeglow feature. The nylon fabric watchband is double layer of contrasting color and looks good. The band is stiff for a fabric band, but is surprisingly comfortable and smooth feeling on the arm. I found myself forgetting to take it off at night. I like the analog/digital combo. The digital area defaults to time. It is small and does not light up with the Indeglow. A single button press brings up the date, which is a plus. There are too many features to the tiny digital area: timers, lap, time zones, alarm, etc. With only 3 buttons to seek and set everything, it can be fiddly. Overall, this is one tough watch that is more than it has a right to be. Great value for the money at this low price point.

A classic, but you need your eyes checked.
Color: Brown/Green/Tan
Looks good for those looking for classic function over flashy. I wanted this watch for the simple analogue time but also for digital features like alarm / date / chrono. I just can't see as well as I used to. If this watch was available in the 42mm range, I'd upgrade in a second. Indiglo and water resistance is awesome as always.
