AMG Clockface 154mm diameter (DE: Ziffernblatt) for adaptation original AMG 360mm brake disc to a Wall clock.

7.8mm hole for a standard clockwork mechanism.

The thickness only of the clock face = 3,5mm

For a mount on the brake disck you need to add the thickness of disk.
I recomend a clockwork with a thread length of 12-14mm.

Photos soon...
