Blender is a free and open-source 3D computer graphics software product used for creating animated films, visual effects, interactive 3D applications or video games.
Blender's features include 3D modeling, UV unwrapping, texturing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, animating, match moving, camera tracking, rendering, video editing and compositing. It also features a built-in game engine.
Blender has a relatively small installation size, of about 70 megabytes for builds and 115 megabytes for official releases. Official versions of the software are released for GNU/Linux, Mac OS X, Microsoft Windows, and FreeBSD in both 32 and 64 bits. Though it is often distributed without extensive example scenes found in some other programs.
This time the tutorial is a text tutorial. Orginally it was supposed to be a video tutorial but it was not to be. Also, for the first time, there’ll be two things at the bottom; the best pictures created with the tutorial, and also some inspirational pictures that go with the tutorial.
The final result:
The tutorial begins.
Start off by deleting the default cube.
Add a cylinder.
Shrink the cylinder down on the Z-axis to an appropriate size.
Go into Edit Mode and delete the middle top vertex of the cylinder.
Extrude the top outer edge inwards about as much as shown, then raise the new edge slightly on the Z-axis.
Also open up a reference picture so that your model is more accurate. Download the reference image here.
Next, extrude your edge upwards on the Z-axis a little.
Extrude that edge inwards about as much shown and raise it upwards a little on the Z-axis.
Then extrude downwards to create the inside of the watch face.
Lastly extrude inwards to create half the watch face, then extrude inwards again. Press Alt-M to merge the vertexes together.
Adjust the watch as needed to match up the reference image as much as possible.
