## Questions & Answers

**Q: To what depth is this watch water resistant?**
A: It meets the standard ISO definition of "water resistant" which means it can withstand being at a depth of 10 cm of water for one hour. This is why the watch is labeled "water resist" without a depth mentioned. A diving watch it is not and I would probably avoid intensive swimming with it. Showering and hand washing are fine. I've used mine casually in a pool a couple times without issue but I wasn't diving under the water.

**Q: What is the length of the watchband?**
A: The length of the watch with strap is 9 inches, or 23.5 centimeters.  It is a simple buckle design, just like a belt buckle.  My wrist is 7.5 inches, and it fits comfortably.  The designers thoughtfully put the longest possible row of holes in the strap, so it should fit on a very small wrist (it should be easy to snip off the extra length of the strap with scissors).  The strap is rubber.  It is very flexible and comfortable.  Hope this is helpful.

**Q: Is this watch atomic?**
A: No is not.

**Q: I can't tell if this is the mens or womens version of the watch.  this seems to be the mens version, but i had the women's smaller version before.**
A: This is the mens version, the womens version is much smaller.

### ⭐⭐⭐⭐⭐ Almost the best budget watch - better than it's sibling!
*by C***N on 16 August 2026*

The F105W is the best watch you can get. I cannot call it the best budget watch as the F91W is still the crowned king, however, with the improvement of backlight with CASIO's Electroluminescence (EL), this ultimately becomes the better watch! It is just as small as the F91W but I've heard that this is slightly thicker. Its small size does mean that on larger wrists, it'll look comically small. For myself, I have a wrist size around 6" and it fits perfect. However, compared to other watches I wear, this does look very small. The resin band is very comfortable but you may find that you may sit between extremely tight, and somewhat snug with enough play for it to move around. The watch being extremely lightweight at 21g enables the watch to effectively disappear on wrist especially because of it being so small in size. The display is very legible, contrary to what CASIO seems to be releasing with other watches as of late, and it remains legible in the most serious viewing angles. If you need to glance at your wrist without moving it on a desk, it'll be possible for you to easily read the time. As mentioned earlier, as it does have EL, low light or very dark legibility is superb and the numerals remain extremely clear. Unlike with the G-Shock Super Illuminator, the numerals stay bold and do not fade. The light is dispersed equally on the entire display meaning that there are no hotspots that you'd see on CASIO's LED illuminated watches. Functions are very basic and are arguably quite rudimentary when compared to other CASIO watches that do not come from the Vintage line. If you're used to something like a modern day G-Shock, Lineage, or other newer cheap CASIO watch, you'll find that the features are lacking but it still has the essentials such as the standard timekeeping mode (displays time), single alarm, and stopwatch with splits. Whether or not you've had experience with CASIO before, it's fairly intuitive to set and understand how to use. The top left being for the light or selecting a setting, the bottom left for changing modes, and the bottom right for start/stop or cycling through to set something. The basic functionality is printed on the faceplate to help you understand, otherwise, you can always find the very thin set of instructions (as there's not many features on the watch) on CASIO's website when you search the module number. Coming from the Lineage to G-Shock, I find that I had grown attracted to these classic watches that I had as a child, but as I didn't want to deal with the poor backlight which is also the charm of the F91W, I decided to find the better alternative. I saw the A168 and then discovered the F105W which may be discontinued in plenty of regions. I love the watch despite it not having much wrist time compared to my G-Shock, but it still brings a lot to the table as it doesn't just tell the time. It comes with extra little features that you'll end up using in a lightweight package that will disappear on your wrist. I'd say that it's more of a statement piece now and wearing it in your day-to-day even in more formal offices will be perfectly acceptable and you may catch some glances for standing out with a classic. Also, what arrived to me was the F105W-1ACR. I believe that this is the American region code and the watch was legit! If you have any question of legitimacy then there's forums to help. I was fairly confident that it was but I decided to consult forums before settling.
