The production of a functional prototype was more complicated than I expected, but at the same time I gained invaluable experience! In Fusion 360, I proposed a design that started from the center of the quartz mechanism that I physically had in front of me. So it was necessary to model the mechanism from exact dimensions in Fusion 360 and model the entire design around it. It was necessary to rework and adapt the entire dial and time indicators so that everything fits into the body of the watch.
On a 3D printer, I printed the body of the clock with slots for magnets, a glass frame, time indicators and a dial. For the production of glass, I chose the process of printing the shape of the glass and creating a mold for the epoxy resin. This solution was only half successful. The microbubbles after hardening were visible, and I gave up polishing the epoxy outcome just before the end because of these visible microbubbles. In the dark, they would reflect the luminescence from the dial.
As an alternative, I chose perspex clear plastic glass, where only the sides had to be processed. For the colors, I chose the procedure of spraying the body of the clock with black spray and clear varnish. I chose an experimental method for the dial and time indicators. Metallic mica powder mixed with varnish preserves the appearance of metal and is very shiny. I applied 3 to 4 layers of this color to the remaining parts with a brush.
For the luminescent elements, I used glow powder and quick-drying two-component epoxy glue. The 1:1 mix retained fluidity for 4 minutes. This process was thus performed three times. The result is very good and has also proven itself on time indicators.
All parts are connected with quick-drying epoxy glue, only the cover is held in place by magnets. The magnets are a perfect solution, there is no screwing, and such slots for screws on the body of the clock would disturb the overall design.
For the quartz movement, I chose a type with a quiet and smooth second-hand operation. The quiet, smooth movement of the second hand is pleasing to the eye and has a more high-end effect.
