This stand is perfect for displaying your watch collection, and can also be used for bracelets or other items. It looks good to me, but I had to paint mine because the top ironing layer didn't turn out perfectly. Make sure to check the placement of the Z seam; I manually placed them on the backsides to keep them hidden.

As usual, I'm including the Fusion360 file so you can adjust the design to your needs.

Dimensions (L x W x H): 20.5 x 19 x 23 cm
Infill: 20% is a bit weak; I recommend going for 30% or more.
Supports: Only necessary for the arm parts. Print them as they are, so the supported side will be hidden.
