This is not correct, I urge you to read a bit about Lorentz invariance, once you understand you will see why your statement does not make sense given special relativity is accurate.
Lorentz invariance means the laws of physics remain the same in all inertial reference frames. Also a spaceship going 99.9999…% the speed of light.
This leads to effects like time dilation, length contraction and the speed of light itself.
The metronome can keep going at any speed independent on the speed of its own reference frame.
