31xx movements with a stronger mainspring and larger balance run for years. Despite the number of new patents introduced in the 32xx movements, there is something (design flaw?) with the mainspring change and the Chronergy escapement that makes the 32xx movement unreliable.

Keep in mind that the power reserve for the 31xx movement has been increased to about 50 hours since the new assembly has been fitted to the movement at service.
This suggests there's more to it all.
If there are still improvements to be made over and above the original specs for the 31xx movement(which suggests there's still life in the old girl yet).
Then perhaps Rolex can improve what they're doing with the 32xx, but they have their work cut out for them.
Who knows, perhaps the new 31xx Mainspring and barrel assembly has a Mainspring that's made of the same material as the one in the 32xx????
Now that's an example of great product developement
