Movement of choice is the automatic Swiss STP 1-11, 28.800 4hz high beat with 26 jewels and 44 hours powerreserve. Leave it to the Swiss who know a thing or two about running like clockwork. A hacking movement makes coordinating time to the second an easy deal. Hacking means you can stop the secondhand at twelve when setting the time and then synchronise with your team. The STP 1-11 allows you to do that and is also equiped for manual winding.
