Don't Buy It!
I bought the LaCross Technology WT-3102B Clock in 2011. Nice looking clock. Unfortunately, it only works when it feels like it. The second hand stopped working repeatedly. The whole thing stopped working several times. After a battery change, it would work for a few days. Each battery change required a get the ladder, climb up to get the clock, replace battery, climb up the ladder, rehang clock on wall, and put ladder back. They claim the battery has to have at least a 7 year future expiration date!! Good luck with that. I finally found some Duracells with an expiration of 7-2018. The clock worked for a couple of days and then the second hand stopped AGAIN. It's keeping time OK except for that.La Crosse Technology WT-3102B 10-Inch Atomic Analog ClockThe DST did work, so that's a plus. I get the impression their Customer Service is to stroke you until you go buy a different clock that actually works.
