How to set up the Omega Speedmaster Dark Side of the Moon (calibre 9300)
Short answer: Pull the crown to position 2 and turn it. The hour hand jumps in one-hour steps and the date follows each time it passes midnight. Then pull to position 3, where the seconds stop, to set the minutes. It is self-winding, but give it a few turns if it has been off the wrist for more than 60 hours.
