I did a quick search and didn't turn up anything. At the most basic - I need a mantel clock. I got an Atmos (I love the idea behind the Atmos), but from where I sit, I can't read the damn thing. The hands disappear in the center hole. From 5 feet away or so it is perfectly visible, but further than that, it becomes a "fortune teller" clock - if you know what time it is, you can tell the time on it. I might return it or move it upstairs on my desk, because it is a beauty. So that leaves me without a mantel clock. I could just go get something cheap and electric off of Amazon, but the idea of a real mechanical clock appeals to me. With 400 day clocks, the rotating torsion is intersting to watch, and it reminds me of a quartz version that my mother had as a kid. But it seems I can only find these on ebay, which I consider that might be of questionable quality. What is the best way to buy a 400 days? Should I save money and get a used one and get the 400 day repair book and get it working myself? Just look at local clock shops? Anything to watch out for? (The atmos I bought I ended up buying from a local clock shop as I bought one off of ebay and it was non functioning so I was able to return it for a full refund, but its made me wary of buying these types of clocks on ebay). Is it reasonable to expect sub 15 second accuracy per day on a 400 day? Any better alternatives for a mantel clock - I'm not opposed to electric, but I generally like there to be something interesting about the clock (for instance we have an atomic clock in our bedroom that we love, but I like the idea that it is precisely the correct time all the time, I have a grandfather clock in the front room with a moonphase, and it's a grandfather clock).
