Introduction: Iconic CASIO F-91W Wall/Desk Size
The Casio F-91W watch ,my favorite classic digital watch and loved by thousands around the world is becoming an iconic retro fashion.
So, why do not to Super-Size it with all the functionality ?!

Step 1: Parts of the Watch
Step 2: Preparing the Parts
I got a 3D model of the watch from GrabCad.com. With my favorite 3D Software: Autodesk Maya, resized it, edited and generated the 3D parts and the outline curves for 2d engraving and cutting. Also a bitmap for the Panel Cover.
Cause the printing size of my 3D Printer (Prusa MK3) and cutting size of the CNC laser Cutter (A3) I had to split the watch Case and the Straps.
3D print, 2D cut and engrave and color print the parts.
Step 3: Getting Graphics From the 3D Model
As you can see in Photo 1, I was so lucky cause all the graphics, letters, symbols.. were on the geometry, were modeled.
Next, manually I create curves for all the graphics following the 3D model. (Photo 2)
When all the curves are done. (Photo 3) Export all them together as .dxf file.
Convert the dxf. file to bitmap (png, pdf...) I did it on a free online service.
Once you get the bitmap. (Photo 4) Edit it in your favorite painting software and get something like Photo 5.
Step 4: Touch Button
Expand a custom touch pad from the TTP223 with the 3D Button parts (button and ring), copper foil and a wire.
Stick the ring with the copper foil into the button.
Step 5: Layout Plan
Stick the 2 parts of the 3D watch case.
Stick the acrylic part to the watch case.
Plan this layout with the electronics components.
Measure distances to cut wires to size following the Electronic Schematic.
Step 6: Electronic Schematic
Use the USB to TTL Serial converter to upload the code from Nextion Editor to the HMI Display. (TX to RX and RX to TX)
Upload the Arduino Sketch to the Arduino board.
Power the Arduino with a 5v power bank or DC 5v 1A adapter. (mobile charger).
Step 7: Top Closure
Following the diagram, stick the Panel Cover, set the acetate shape and close with the Frame.
Step 8: Straps, Buckle and Free Loop
Stick the Strap parts.
Stick the Buckle parts.
Mount the Free loop.
Now stick both Straps to the Watch case.
Step 9: Back Case
I have also prepared the Back Case
Step 10: Conclusion
I am very happy with the work done. It looks so nice to me.
Hope do you like it too !
