The service life of a watch mainly depends on the quality of the watch movement and the waterproof and shockproof effect. Dumet's movements are Swiss ETA movements that have been polished twice, just like Omega and Longines. The waterproof standard of Dumet watches is also the highest among Swiss watches of its kind, generally more than 50 meters, especially its first cork waterproof, which has always been recognized as the most advanced waterproof technology in the world. Of course, it is not to say that it is shockproof. Dumet watches are carefully designed, both in case space and movement components. Therefore, there is definitely no problem with Mido watches.
