I looked at all of the different watch box cases and I am so glad that I chose this one! It is well made and looks more expensive than it was. I love that I can see everything at once instead of having to open drawers to only glimpse at some of my stash. I bought this for my 20 watches and even though I can't fit my small wrist watches on the pillow because this is made for a man's watch, it really doesn't bother me. It's easier to take out a watch or put it back. It really freed up a ton of space in my jewelry cabinet for my jewelry! Love it!!!

Good case

Color: Black

Great watch case. Fits all my 43mm-48mm watches. Any bigger they will run against each other. But altogether a solid purchase.
