Query: Great clock! Nice and big, easy on batteries!

I am using this clock indoors, very nice looks and large enough to use on a big wall without looking "cheap". The main concern I had before getting this was the battery life, I have heard bad stories about some atomic clocks using up a battery(s) in as little as 30-45 days, but since receiving this 3 months ago, it's still going strong on the first charge of the rechargeable battery I put in. I really like the fact that I can easily tell what time it is from across the room and down the hall without my glasses even being pretty badly near-sighted.
