This is the most likely scenario, and it can happen on any watch. In fact some Seiko movements are notorious for it, and as you mention the solution you will often see on watch forums is to give the watch a smack into the palm of your hand (not something I recommend personally).
This is in no way a sign that a watch is rugged, or up to the job - it's more bad luck as the shock has to happen in a specific direction at a specific moment in time for the balance spring to get snagged on the stud. One of the msot reliable and ribust movements out there is the ETA 7750, and here is one with a snagged balance spring:
From above:
After "de-snagging" and some adjustments to the spring were required:
If you think other brands don't have this happen, well here's a Rolex with a snagged spring:
And what it should look like:
In the end it would have been a very simple fix for any competent watchmaker, but since the OP had a tantrum and let the watch sit for so long, it will now need a full service that will be much more expensive than either the fix would have been at the time, or what the full service would have been.
