how can i put back together my rotary wrist watch gb00471?

start with the big cog, filling the largest empty space, then choose the next largest cog, wedge that in the bottom corner. put all other parts in a small bowl and slowly tip into the back. put thumb over aperture and shake violently. replace back plate ensuring water ingress seal is suitably seated. place next to ear and listen for electronic ticking. if no noise replace battery
