The following practice activities will help you improve your 3D modeling skills.

Google the reference images of the watch you want to model. If you want to make the same watch from this course, look for Rolex Cosmograph Daytona pictures so you can look at the watch from different angles. Save those images in the References folder of the project.
Set up the reference images in Cinema 4D. I'm attaching the reference images for the Rolex Cosmograph Daytona watch. You can download the Front and Side views to model the Daytona watch.
Follow along with the class and model your own 3D watch. Then, texture it and light the scene. And finally, make a few renders from different angles. It may take you a few hours to complete this project, but the end result will be worth it.

Here you have the reference images (front and side views) to get you started.
