Review: Nothing like the original - This watch is a timeless classic, it’s super comfortable. Perfect size for any wrist, large enough screen to easily see the display. The quality is unmatched, and my personal favorite is the black light, it’s a full screen light up that alone is the main reason I purchased the watch. With the color, comfort, and price you can’t go wrong.

## 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.
