mixed feelings about this. on one hand i am 100% for making things last as long as possible if they still function. on other hand i am not sure this clock actually "functions" by modern standards.
i mean even if it runs as well as it did on day one it will simply never be as accurate as a clock that is synced to the internet or to the atomic clock radio signal or clock signal from GPS satellites.
recently i realized my windows clock was out of sync with my phone clock - turns out the option to automatically set clock in windows was turned off - i was annoyed by that but it was an easy fix.
bottom line - i would never buy a clock or watch of any kind if it wasn't always accurate to a fraction of a second, which is only possible for a clock that is synchronized to an external accurate source.
that's just me though. my 98 year old grandma loved having lots of clocks even if some of them were off by like 20 minutes. her main issue was she didn't know if the time was AM or PM so i would have to explain to her that " it's 10 o'clock and sun is shining so it's AM " and so on ...
my other issue with your clock is redundancy. i hate it when things are redundant for no reason. i try to keep multiple copies of all my data because i don't want to accidentally lose it. but you don't need to keep multiple redundant copies of time that all gets synchronized to the same atomic clock.
that said. although i used to buy furniture new in the past i have switched to 100% used furniture now because a table is a table. i would rather spend money on computers because a new computers is actually different from an old one.
