Accessories

Style
The look of the 3500 isn’t far off from the 6000. The most significant difference being the digital display. Otherwise, the 3500 looks equally adventure-ready.

It’s comparable to the 6000, the most prominent difference being its digital display. Users of the 6000 will find the 3500 just as useful.
Advanced Features
The Pro Trek 3500 has all the same advanced features as the 6000. The watch includes Triple Sensor Navigation technology, which provides users with information on altitude, barometric pressure, and a temperature sensor. A compass adds another navigational element. The Pro Trek is also water resistant up to 200 meters. Another feature it has in common with the 6000 is its Tough Solar powered technology which is behind its outstanding battery life.
Connectivity
The Casio 3500 does not have Bluetooth or WIFI capabilities and thus cannot connect to other devices such as a Smartphone or computer.
Ease of Use
The Pro Trek watch features large simple to push buttons. The buttons feature smart edging so that accidentally pushing them is less likely. The intelligent design features ensure accidental presses are kept to a minimum. Using the actual watch does take a bit of know-how, though. You’ll need to pull out the manual if you’re not already a Pro Trek user. Getting to know and work the navigational features is likely not something a beginner will feel comfortable with.
Power Source
Like its Pro Trek cousins, the 3500 features Tough Solar Power technology. This makes it easy to charge on the go and away from outlets in the wilderness. The maximum battery life of this digital device is up to 7 months.
Accuracy
Compared to its predecessor, the 3500 boasts improved accuracy thanks to its use of Triple Sensor feature and improved sensor technology. Users report that the atomic clock is exceptionally accurate and agreed that the Triple Sensor technology also proved to be very accurate. According to reviewers, the temperature was the only reading that could be off significantly because of body temp interference. Some reviewers felt the compass was best used as a secondary navigational piece due to its slow response time but felt confident that accuracy was good enough for most use cases.
Face
The 3500 keeps the same round watch face of its sister watches. It also features a rotatable stainless steel bezel with navigational markers. The most significant difference is the inclusion of a digital screen instead of an analog one. Reviewers mention that the display has a slight tint to it, but it’s still reasonably easy to read. Some users did find that compared to the size of the watch itself the display is pretty small, but thankfully the text is large enough that squinting isn’t necessary.
Band
The Pro Trek watch is available with metal or resin band. Each made of quality materials. The only drawback with the band is that it’s tough to fit over clothing, which is a necessity since it needs to be uncovered to work accordingly. This is a problem reserved for the titanium band, thankfully, since it’s not as easily adjustable as the other strap options.
Apps
Because of its lack of connectivity, the Casio watch is not compatible with any applications. The watch is meant to work and be used entirely on its own.
Sizes Available
The 3500 is one of the smallest options in the Pro Trek range but is slightly bigger than its predecessor, though not by much. The casing measures 53.4 mm wide and 14.5 mm thick. The overall weight is about 88 grams. The Casio has a nice weight to it, and it feels nice worn on the wrist, but women and men with small wrists may find the watch a bit bulky.
Durability
The Casio Pro Trek 3500 is water resistant up to 200m, which is better than the previous version’s 100M rating. In terms of outdoor temperature, the watch is resistant down to -10 degrees Celsius.;Reviewers mentioned that they took the watch on intense outdoor excursions, including rock climbing, and came away with their Pro Trek in one piece.;The screen is scratch resistant and shock resistant, though some noted the mineral crystal screen was a magnet for scratches. It might be a good idea to buy a protector for the screen to prevent this from happening. The watch is perfectly capable of handling severe weather fluctuations, too. Compared to previous versions, the Trek is designed using steel over aluminum for a much more durable construction overall.
Price
Less expensive than some of the other Pro Trek models, reviewers thought the 3500 was a good buy. The watch does come in a premium Titanium version that is a lot pricier.
Bottom Line
The Casio Pro Trek 3500 is for the outdoorsman or woman who wants a sophisticated, sturdy timepiece with navigational abilities. The watch features an incredibly long battery life and boasts exceptional accuracy. It’s a good choice for those who want the features and functionality of the 6000 but without the analog display. The digital adventure watch is a simple beast with high tech classic features. You’ll need a bit of know-how to operate it, but once you get the hang of the 3500, you won’t want to take it off.
