It is CW if you are facing the engine. You can tell also by spinning the engine using the starter motor - tie down the shut off valve if you do NOT want the engine to start.

You can turn the engine whichever way you want, it is not going to jump a teeth on the OM603. It is physically impossible for the timing chain to jump a teeth if turned backwards ( CCW ) as the TC is restricted in 2 places, near the IP and the oil chain.
