To what depth is this watch water resistant?

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.

What is the length of the watchband?

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.

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.

This is the mens version, the womens version is much smaller.

The best watch ever

the best! so glad that discovered them. been waring the f91-w for many years and hated their faint backlight that barely worked. This watch has all the awesomeness of f91-w with an amazing backlight

Perfect beater watch

Love the design like the GOAT f91w but with a much superior back light probably the best light on a Casio
