To the question, no power reserve in previous Rolex models.
If Tudor marketing believes the PR feature has helped sales then perhaps you’ll see more PR indicators in the future on their models.
As for Rolex future with PR, I could see it for a model where elapsed time is a key feature. For example in any of the divers as a safety feature whilst diving. Or the Daytona in the case of event timing. Having a watch stop during that important timing function could pose a real problem.
A small window on the dial could tastefully display a color applied to a disc underneath. One that starts at green and then gradually rotates as the PR reduces. Gradients from green to yellow to orange and then red.
But let’s agree that a small fraction of those model’s owners ever use the elapsed time function - that is, beyond the time measured to flip a steak on the BBQ...
