A while ago I saw a render of a similar watch on Pinterest. But there was no further content about it. So I tried to actually make a similar design here.
For the glass bricks, I poured epoxy resin into a mini ice cube mold made of silicone (If you look up “mini ice cube tray” on amazon, you should find it directly). Then I placed them so that the dented side was facing down and organized the cubes into an approximate circular shape. Then I filled the joints with plastic glue and let it dry. After drying, I drew the inner radius of the outer_ring on the resin sheet and then cut out the circle shape with a dremel. And because I don't know anything about polishing, the only rework was a light manual sanding of the edges.

For the clock mechanism, I used one from a clock from the dollar store. Accordingly, the dimensions on the clock hands and the cutout on the back may not be suitable for everyone and require adjustment.
The print settings are basic, as the parts are not under a lot of stress.

In the end you can put everything together and secure it with two M 1,4x12 screws (I had these lying around, please adjust the model as you like)

Since I am not yet satisfied with the resin front plate, I am planning a second attempt in the future, updates may follow.
