  • The BEST WATCH under $15. Terrorist or not.
Color: Black
Well. I contemplated for some time if I should write a review for this ultra affordable watch or not ... after some thoughts, this Casio deserves every bit of my highest recommendations so I decided to go for it If you are reading this ... either you stumbled on the F91W-1 by looking at some of the cheapest Amazon stocked watches Or you read from Wikipedia, or some watch forums, or other sources that this Casio is the favorite among the terrorist group. Well regardless what your motivation is ... this watch is worth every penny. Some background information. I been collecting mechanical watches for about 16+ years. And right now I own over 50 watches... From this humble $11 Casio to a few Rolex, Zenith, Omega, JLC that cost 500 times its price. I also service some of my own mechanical pieces. Although I do not have much experience with quartz watches. I do know quite a bit about material, design and many aspects of a proper horological machine. And the down right truth is, there is nothing this Casio can't do. As far as a practical machine, it can beat up your datejust/ submariner any day of the week. (Although this might not be that big of a deal in todays cell phone oriented world) Pros: It is designed to be simple and intuitive, the trait of most Casios. Button placement and functions are down right instinctive once you use it for a day or two. It is deadly accurate (duh), its quartz. The battery life is an amazing 7 years (given you use certain functions only once or twice a day.) Although some "upgraded" version has 10 year or solar battery. The battery life is more then reasonable for any practical purpose. This is the most comfortable watch I own, due to one reason - the weight. It feels like you are wearing a feather or nothing at all. 20 grams to be exact... or 0.7oz. Crazy how light this thing is. The retro styling is another plus .. it may not have been cool in the 80~90s. The nerdy black resin square case is now hip again... The construction of this watch is very well thought out to simplify the manufacturing process. Which, btw, is done in Thailand. Case is a single piece resin with slightly protruding plastic crystal. All the electronics are on a one piece of ic board. The case back is made from stamped stainless steel, secured by 4 screws, and the interior is where the alarm speaker goes. A rather large rubber gasket surrounds the movement. Light weight rubber strap with some mysterious reflective inclusion. Cons Water resistance: The case construction does not allow any serious form of water resistance... as a matter of fact, in the Casio manual they do not recommend anything more then hand washing. The real problem is the pushers, they lack any gasket so water will pour in when use underwater. The tolerance of the case and SS back is decent. But the gasket sits too low so a 100% secure seal will not be possible. Crystal seems to be glued into place, so no problem with water there. I think degrees of water resistance is how Casio separates their cheapest products from the slightly more expensive one. You can hear something rattle when you shake this watch ... it is nothing major however If you are used to today's super large watch... namely, Graham, Panerai, 44mm, 50mm or the likes. This watch will look puny to you at 35mm. But if you like most watches in the 70s or 80s ... this is just the right size. The bottom line is ... this is a hell of a watch for the money. As utilitarian as it could be yet possess some of the funk from the past decades. It also carries a good amount of interesting back stories if you tell people about its popularity among the terrorists. A great watch! And the best $9.99 I spend on a watch. ... show more

  • Fits my peculiar needs perfectly
Color: Clear
My new Casio F91W-1 Classic Resin Strap Digital Sport Watch with white face and clear plastic wrist band is what I needed for a particular purpose. I need something about once a week that is very inconspicuous. I'm not trying to hide it, but I don't want it to grab peoples attention. Just be there doing the job without being in the way. This fits the bill. The photos give you a good view of how clear the band is. It is small for a full grown man, and could easily be worn by a woman or younger person, but again, that fits my purposes very well. The digital readout is clear and easy to read. The buttons are large enough and protrude enough that that are easy for even elderly fingers to push for the light or to change modes or set the time. As far as accuracy goes, I'm very satisfied, but not thrilled. Comparing it to the world clock official time it has gained approximately 1/2 to 2/3 second in the past week. "Your mileage may vary". That's really pretty good. That means I'll only have to reset it every month or so and only then if I'm really obsessed with accuracy to the second, which for my purposes is not necessary. For a convenient, pretty accurate and very budget friendly time piece this watch really checks the boxes for me. I've had good luck with Casio in both quality for the price . . . or "value", and functionality in the past. Of course, if something changes in the next few months to a year or so I'll be updating this review. ... show more

  • Awesome watch
Color: Black
This is my second of these watches. My last one lasted a long time before I snapped the band so I decided to get a new one, this time with a gold face. It looks really nice, has all the features you'd need. I like that it shows the time and the date without having to hit a button. The light isn't very bright but it's enough to see the display in the dark. I shower with it every day and it holds up. Just what I needed and wanted ... show more
