Chronographs built with a lateral clutch can hardly avoid the jarring start of the second.
Even chronographs with a vertical clutch system, there is a some backlash in the gear system. That is to prevent the gear train from locking up.
MB&F makes use of LiGa technology.
I have doubt there will not be any wear and tear.
About LIGA
An extract reads
using Mimotec's UV-LIGA technology. These gears mesh together with a virtually a no-tolerance/no-play engagement. Normally, gears interacting this tightly would bind; however, Wiederrecht's patented asymmetrical-split-tooth gear design ensures this does not occur. The high precision of this gearing enables very accurate time-setting and offers high reliability.

Talked
About this with my friend Romain, a watchmaker at Zenith, he told me that there is no great problem in doing this. Just wind the watch about 30 times to charge enough and then,.. wear it. Grtz,Dom
The lateral clutch engages gears of different shapes.
The clutch wheel has ellipsoidal teeth because they are constantly engaged with the wheel on the back of the fourth wheel shaft. But the center seconds wheel has very small sawtooth teeth (two teeth for every one on the clutch wheel) to minimize jumping o...
