If you’re into wristwatches, like me, and are also a fan of the Sketch app (or just want to get better at it), then this is the tutorial for you. In it, you will learn how to create a very realistic and detailed vector illustration of a watch using basic shapes, layer styles and cool Sketch functions such as “Rotate Copies” and “Make Grid.”
You’ll learn how to apply multiple shadows and how to use gradients, and you will see how objects can be rotated and duplicated in special ways. No bitmap images will be used, which means you will be able to easily adapt the final image to different sizes and resolutions.
