Clock face carved from 9mm birch ply. Designed with Vcarve Pro.
The quartz clock module had too short a spindle so I counter sunk it into the back of the workpiece - lining up was simple - carve, drill centre, cut out the circle, flip it and centre it in the waste piece (lollipop sticks!) then clamp down and cut the pocket.

It would be nice to add some parameters you used for your nice clock!

I did! I said
9mm birch ply
😉
You want more? Here you go:
Centre pattern: v-bit 60 degree, 6mm
Text: v-bit 60 degree, 2mm
Centre hole, profile cutout & back pocket: 3mm spiral upcut, 2mm pass
All run at 20,000 rpm, 1200mm/min feed.
Total run time (SC600, HF350 spindle) was 1 hour 20 minutes.
Using the 6mm v-bit for the pattern is a huge time saver. Text at that size isn't sharp enough from a 6mm bit though, so I used the 2mm v-bit for that.
I ran the 6mm v-bit along the outside profile to a depth of 3mm, so it leaves a chamfered edge when the final profile is cut with the 3mm spiral upcut. I find this a useful technique with plywood where sometimes the upcut spiral causes a little tear-out. Yes, I could use a down-cut spiral but they clog (cutting through 9mm). And I contemplated doing the first pass with a down cut then changing to upcut for the rest ... but life is too short!
