The short answer to your question is "Yes".
The long answer is that unfortunately, there is no clear answer to this question, regarding the Zeiss or any other scope brand. This is because there are so many variables to the stresses your particular scope will be subjected to. What load are you shooting? does your rifle weigh 7 lbs? 12 lbs? Is the scope precisely and properly mounted, or is there some misalignment? If so, how much? Is your scope subject to rapid temperature changes? How many times will your scope be dropped, knocked or bumped, and how hard? The average variable riflescope has something like 55 parts and 10 to 12 lenses, any of which can fail, even on top of the line $1500+ scopes. They are made by people after all.
All that said, a quality scope like the Zeiss is far less likely to have problems than other scopes. One of the most common scope failures is a broken reticle. The Zeiss reticle is not a bit of wire suspended inside the tube, but is actually etched onto one of the lenses, so this failure cannot happen with the Zeiss. A quality manufacturer (like Zeiss, Leupold, Burris, etc.) that stands behind their warranty is a good indicator that your scope will very likely hold up. Personally, I would not have bought a Zeiss Conquest if I did not have confidence in it's durability.
