Technical differences between Rolex 32xx and Tudor MT?

With reference to the power reserve.
Regretably i was referring to the 31xx movements previously discussed which have gone from a 48 hr original specification to a slightly improved 50 hrs with a simple Spring barrel assembly change as part of routine servicing at RSCs.
It's an example of what's possible under that principal of swaping out sub assemblies or even entire assemblies with sufficiently strict QC underpinings

Ah, I gotcha . Yea, not unlike how the PR on the 22xx was extended not long ago (not sure if that had to do with the introduction of silicon spring or something else).

Yes, incremental improvements are always nice, and if they could, for example, keep a fundamentally flawed design working properly in five-year intervals (vs. one or two-years) that would also satisfy most.
