Except the watch won't kill you if it decides to malfunction.
I have read up on these tourbillons and they are quite capable. Obviously no where near in the same league as JLC master tourbillon and the likes, lacking in the precision and the finish of the pieces but they are certainly reliable enough. Plus, prices for Swiss watches are inflated on reputation alone. We all know, for example, Japanese movements aren't in anyway inferior to Swiss, Swiss is just more marketable.
In certain circles, it will kill you, socially.
Also, if reliability is all your number one priority when looking for a watch, then why would you buy a Chinese tourbillon? The idea of a tourbillon (or any mechanical watch) in this day and age is to show off the "precision and the finish of the pieces". If you don't have that, you have a gaudy wrist weight.
Get a $10 quartz, it will be more reliable and accurate. And it won't be trying to be something it is not.
And forget the Chery, buy one of these:
