An open mechanical pocket watch

A study of an open mechanical pocket watch with exposed gears and a short chain on textured paper. Align the circular case and open hinged cover in perspective.

A way into the drawing

1. Establish the construction

   Align the circular case and open hinged cover in perspective.

2. Resolve the main structure

   Place the largest gear centers within the case before adding smaller gears.

3. Develop the detail

   Connect the crown, bow and short loose chain.

4. Control the values

   Separate dark gear gaps from bright metal rims with controlled graphite values.

A small thing to tryMake adjacent gear rims meet before drawing the small tooth pattern.
