Nope, in fact they are magnitudes less impressive than analog watches with actual moving parts fully exposed on a persons wrist, which are working still today.

You can find alot of more advanced technology, even with moving parts, computers, vcr, gaming consoles and much more, which are still working (and obsolete). Even though people may argue that the alarm clock is not obsolete, it is. The reasons most of us have upgraded or replaced it with our phone are several (lack of settings for weekdays and alarm for events several days ahead, lack of bluetooth and lousy speakers, old design, lack of option to wake you up with light instead of sound, lack of transportability, unreliable as it doesn't work and resets if power goes out). There are many reason why they have been stuck in a box, along with the still working vcr player. Nothing special about them at all.
