Thanks Padi for your explanation.
Since the newer non -C Subs (with the engraved rehault) has the parachrome blue hairspring and shock system, I am surprised that Rolex still calls it caliber 3135.
One would expect it to have a different caliber number.
In the future, is it possible that Rolex will replace the Navirox hair spring with the parachrome blue hair spring when it is sent in for service assuming it needs to be changed? Same goes for the "shock system"?
Thanks in advance !
