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.

Men’s Watch Box w/24 Slot Display

Color: AllBlack, Color: AllBlack

This mens watch box looks amazing, and nicely fits 24 watches without worrying about damage to the other watches. Each slot has its own location, and not need to worry about the watches rubbing up against each other.

Nice case

Color: Dark Brown, Color: Dark Brown

Very nice case. Good presentation. Only issue is if watch is over 52mm they can make it a tight fit.

Nice Case with clear top for 24 Watches

Color: Black

This is my second watch case and I am very happy with it. I like the glass so you can view the watches from the top. This one has a flip up latch which I also like because you can reach down and open the case with one hand. The pillows are a good size, not too big so they do not stretch out your watch bands. I specifically wanted a case to hold as many watches as possible and 24 is about the biggest I could find in this configuration, meaning a box and not some kind of cabinet which I do not have room for
