Pocket Watch development/iterations

I decided to choose the idea of the sundial pocket watch because it seemed unique but rather practical. I have not had much experience of drawing pocket watches or sundials in great deal so I started of with some basic sketches and drawings. After I felt confident enough with the shape, I started to think how a sundial would comfortably fit in without damaging the lid and what angle the sundials shadow would be. I  then started working more with the idea of colour and how light sources effect the round surface of the pocket watch .
