A 24 hours test can be simulated by releasing a couple of ratchet wheel rotations.
This problem runs so much deeper than just migration of lubricants and a pivot that occasionally wear out prematurely.

That would mean a fundamental 32xx design problem! Not solvable since the introduction of the 3235 and 3255 in 2015?
Consequence: the movement failure rate (very low amplitudes after full winding) during the 5 years warranty period is extremely high for all 3235, 3255, 3285, 3230, and not only for watches sold in 2015,16,17,18…2022.
