If I recall all of the upgrades were in place by 2008, so yours should have had them if the watch was new after that, or if it was serviced after that time.
When I service these (3301, 3303, or 3313) I always let my client know that there will be potential parts that require upgrading. Also for service, you don't need to go back to Omega, but you do need someone who is familiar with that specific chronograph movement. Oh and of course has had co-axial training if it's the 3313.
Cheers, Al
