Create Watch - What do I need

Hi community,

I am new to unity and I would like to know what are the best tutorials, books to create a clock/timer with tick sound. The timer is just an example, but what I understood is I need 3D Objects, Textures, colors, shader and any more..

So I would like to understand when to use what and why. I also often read to use Blender for specific objects.
Do I really need it or when do you thing its meaningful to use it.

So if you have some good advice and links / books on how to start explaining each it would help me a lot.
There are tons of tutorials but I am a bit lost as they are so many and if I really need them. Thus I took the clock/timer as an example.

Thanks for any advice in advance
Ralf

 

I used Blender for those purposes mostly
