Good functionality, but DON'T buy...

  • Familiarity:I've put it through the wringer
  • Fit:True to size

This watch is good looking, has lots of features, at a discounted price is especially reasonable, but in my mind one thing ruins it all, and it is sadly VERY preventable. The watch features says the band is made of resin and textile, or what looks like woven nylon. The only thing resin about the band is the loop to keep the watch strap close, nearly the entire band is made of the textile nylon material instead of resin. Also, the strap is lined with a thin black, paper thin fabric that runs most of the length of the watch band strap. The issue? First, with regular, general, not heavy, use the paper thin black lining on the woven nylon band comes apart and ends up hanging from the watch band, leaving you to annoyingly pick it off. So why that feature? To protect the nylon woven band that is equally poorly built and which begins to fray in no time. Initially no big deal, but after just a little time it completely brings down the overall look and quality feel of the watch. Additionally, the nylon material will rub and irritate your wrist with extended use. The worst part is how this went unnoticed in Casio R&D. So easy to have prevented all of this and just made the band all resin. I am giving 2 stars because although the watch itself and it's functions are good, the frayed mess you will be left with would not have me buying this watch ever again until a design change is made, and 3 stars would skew you to thinking maybe you should consider purchasing it... Please rethink your decision and happy hunting.

My First "Swiss Army Knife" Watch

  • Familiarity:I've put it through the wringer
  • Fit:True to size

I've had this watch now going on two years, and I've put it thru multiple backpacking trips, hikes in the Chisos, the depths of the Grand Canyon, whitewater excursions on the Spokane River, and my weekend mountain bike rides in the Central Texas heat...and, it's still in great shape! The compass is accurate, and the barometer is nice to detect inclement weather. But, the wristband does get a bit funky from sweating...that's what you get when you have a nylon/fabric wristband.

Hi, thank you for your question.

Yes, the watch is all black- with the yellow N arrow at the top of the watch face.


Great Watch

    I do a lot of stuff outside from planting flowers for the wife to catching trout in the ozark mountains and the watch is durable. It has more feature than I thought I would wver use but I find myself using the barometer and compass more than I thought I would.
