PRG601 Series | Pro Trek | 100M WR | 1/100 SEC Stop Watch | Compass/Alt/Baro-Thermo | Tough Solar Power/Atomic Timekeeping | 1-100 SEC Stopwatch | Countdown Timer | World Time

Most Casio Pro Trek watches look like Pro Trek watches. They're bulky, angular, and covered with words describing every feature. This watch has all of the Pro Trek features you would want, without the chunky aesthetic. It's solar, but doesn't say 'tough solar' in large print on the bezel. The backlight button is unlabeled. The function buttons are labeled, but the print is small and on the dial under the glass. In fact, most of the text on the dial is subtle. The one exception is the orange 'BAROMETER' text on the mode dial, but it's not too big and the color looks good with the other orange accents. The large white numbers and hands are easy to read against the dark blue face. The positive digital screen is easy to read, and has a slightly blue tint that matches the blue theme of the watch. The dark blue bezel is a nice color, and it pops nicely in direct sunlight. The engraved time zone indicators are small and a little difficult to read, as they're black on dark blue. It's a large watch, but it's lightweight, so it feels smaller on the wrist. This is likely due to the construction, which is primarily black plastic. Even the back cover is plastic, though it feels like a high quality, durable plastic. Other miscellaneous things: The crown screws down, for better water resistance. The buttons are large and textured, and easy to press. The orange second hand aligns with the indices perfectly, and adds a nice contrast to the blue theme. The lug width is 23mm, which is an odd size, but there are strap options out there. The fabric strap that's included is comfortable, though I wish the hardware was black instead of silver to match the aesthetic of the watch.

I sold my Citizen and Seiko and this is now my daily wear watch. I'm not careful with it at all, it's taken many bumps and whacks, and still no issues as all other than scratches on the bezel. This is a BIG watch but I love big watches personally. 54mm lug to lug. In other words the total length of the watch body. (The official Casio measurements for the size are incorrect.) But it's very light and comfortable. Plastic body with metal bezel. Lovely blue bezel that will scratch and the metal under it will show very visibly. But that's okay just enjoy it. Consider it "battle damage". The blue bezel looks bright or dark depending on lighting. Only around 42g weight without strap. I added a Wocci FKM rubber strap that I got on Amazon for around 20 bucks and I think it's good value. Very very comfy. The included fabric strap wasn't what I like. Good LED light. Amazing lume that lasts all night without me needing to point a flashlight at it. Better than anything I've owned including Seiko and Citizen watches. The watch itself is also solar powered. I don't go out much so once in a while I put it in a bright area to charge. No wireless connectivity but it's easy enough to change the time with the digital crown and buttons. Cool features for selecting time zone and switching back and forth super easily. Cool stuff like digital compass (points with seconds hand). Very quiet. I only hear it ticking from around 6 inches from my ear if the room is very quiet. Good peep and alarm loudness. No hourly chime. Four or five daily alarms. Very easy to use times. Countdown is adjusted using the crown. 23mm strap size which is less common but easy enough to find. And if the strap is soft then 24mm easily squeezes down to 23 and it's nearly impossible to notice. That's what I did. I also tried some other straps like a Speidel brand expansion bracelet in 23mm that I didn't like very much and a 22mm magnetic mesh bracelet that worked great (only the digital compass doesn't work if that bracelet is attached but i had no issues after removing it.) I paid around 200 bucks for this watch and I think that's amazing value. I included a photo of the lovely titanium Casio LCW-M100TSE as a smaller alternative to this. 44mm lug to lug and only 9mm thick. I'd love to see this but duty sleep tracking

This is sharp looking pro-tek. Fits super comfortable and easy to read. This is my second pro-tek and I love it. The strap could be better for the price but its ok. Took off one star for that. Great features and look. PLEASE NOTE THIS IS A 23MM STRAP NOT A 24MM STRAP. Odd width but you can still buy select straps for it.

I'm 78 years old and really appreciate the easy to read (time) watch face. I use none of the "complications" on the watch other than occasionally the stopwatch and countdown timer. I don't need the other features other than the day-date and illumination. The lume on this watch is better than most of my usual diver watches; I can still read the time in the dark after 6+ hours. Amazing. Of course, the LED lights everything up nicely if needed. I will replace the OEM watch band. My wrists are small (around 7.5 inch) and I do not care for the metal keepers. They get in the way, and of course the watch band is very large. I could cut it down, but those metal keepers are still there. I am replacing the watch band with something else, probably another silicon dark blue one. Yes, it takes a 23mm watch band like someone else said. The description by Casio is incorrect.

Great watch. As good of a non smart field watch as I’ve ever had (Garmin is great if you want the extra capabilities and distractions). Will say the temperature gauge on it is rather meaningless because your body temperature obviously impacts the reading. But I do enjoy the ease of the barometer, altimeter and compass functions for hunting. Wears great. Bought an extra 23 mm strap but haven’t swapped it out. Surprised by how good a feel the OEM strap is.

Love the watch! Hate the fabric band. The watch is great, it has a big bold face, keeps accurate time and has some functions that any outdoorsy person is gonna dig. Altimeter, compass, temperature, stopwatch, I can go on and on. The band is terrible. After wearing this for 3 months the hole that I set the post into has already stretched out so the watch is loose on my wrist, it's a personal thing to me, it's a watch not a bracelet, plus the metal ring that keep the band in place slips all over the place. Anyhow, gonna buy a silicone or rubber band to replace the lame fabric one. YES, I do suggest it, I would buy again...

Good watch and cool design . Very usable on outdoor activites,the compass work great. Was done comprasion with professional measurement army equipment. Excellent value for money.

Just got it a week ago, so far I really like it! The soft fabric band feels very durable and is super comfy! Not sure how I feel about the resin case--hopefully it will hold up over time (pun intended....) One good thing about the resin case is that the watch is very light for it's size. I do worry about one of the band lugs breaking off though--which would render the watch useless.....I love the size of the case and I'm a big guy! the watch is very easy to read, love the blue band and watch face, the LED lights are SUPER bright, and the watch is easy to adjust. Also really love that it's solar--so no watch batteries to replace! I do wish it was either Bluetooth or could connect to the atomic clocks for accuracy--I know some other Protek models do that. All in all I'm really happy with this watch so far!!
