Today I was finally able to complete the first prototype for my frontplate antenna.

A few days ago I bought these engraving bits for my CNC and put them in good use for the frontplate design:

I wasn't expecting much, not having every tried to engrave acrylic with these kind of bits, but I was pleasantly surprised by the results

We could argue that the "T" didn't came out so great but I'll keep it as is.

Time for the final assembly...

I used some 2mm thick double sided tape to glue the frontplate and the connection seems to be good enough. A big plus for me is the fact that the tape is completely invisible from the outside.

And now some final shots.

All in all I'm super happy with the results:

The only downside for now is the fact that the watch is not water proof anymore. Nothing some glue can't fix though... But it's for a later version.

Some more improvements that came to mind:

Overall I had a lot of fun with this project, I hope I'll find the time to keep improving it.
