La Crosse TechnologyLa Crosse Technology WT-3102B 10-Inch WWVB Self-set Analog Wall Clock and automatic DST reset,Black/silver

I like the clean modern style of this clock, with a ten inch diameter it's a bit small for mounting on a large wall but for my application in a little room and smaller wall in a nook it fit perfectly. The clock functions as reliably as most of quartz movement type battery clocks with the added feature of receiving the WWVB atomic clock signal out of Ft. Collins, CO. making it accurate to within a second every 300 million years. The set up was easy, even though it has an incrementally advancing second hand the clock is silent enough running that I can not hear it within 3 ft which is nice for my bedroom location, the clock is not mounted on an exterior wall or close to a window but still received the WWVB signal within 2 hours of setting up. The knowledge that this clock is synced to WWVB appeals to my sense of science and history of striving for accurate time keeping..... knowing that the clock is associated with the same technology that helps navigate the ships at sea and satellites in space is pleasantly satisfying.

I like everything about this clock. The size was perfect for my bathroom. I was looking for an analog clock design that had the atomic feature. I purchased another similar clock a week earlier, but after trying to get it to work for several days, I gave up and returned it. I took this clock out of the box put in the battery and within 5 minutes, it received the signal and set itself to the correct time. So far, it has kept the correct time down to the second.

Many 1 and 2 star reviews for this clock date back to 2007 and are outdated. Hopefully, a review can be up-voted enough to replace those outdated ones. Otherwise, all the old reviews are really doing La Crosse a big disservice.As of Sept. 2014, the La Crosse Technology WT-3102B has two switches in the back, one to set the timezone and the other to set DST on/off. There are also three buttons. Set, Wave, and Reset.Operation:When you first insert a AA battery, the clock will reset itself to 12:00. The clock will then begin to adjust itself to the correct time.- Set button -- This button is for manual time setting. Hold it for a few seconds and the minute hand will start to move. Press it and the minute hand will jump in minute increments.- Wave button -- Hold this button to force the clock to look for the Atomic clock signal.- Reset button -- Resets the clock to 12:00 and start again.Good:- COMPLETELY SILENT (not really, see update) -- When you first insert a battery. The clock resets itself to 12:00 and begins to increment the minute hand at high speed to get to the correct time. What you'll notice is that even though the clock gears are grinding at high speeds, you hear NOTHING. No ticks and no tocks to mock you on those insomniac nights. No being woken up at 2am because the clock is automatically adjusting itself for DST (I had a clock that did that. Scared the crap out of me).- Easy to use -- Insert the battery, hang it up, have a cup of coffee.- Peace of mind -- I bought three of these clocks to replace cheap clocks that were always going out of sync after just a few weeks. It's great to be able to look at the time and know that it is accurate.Bad:- Manual time adjust mode -- Having to hold a small button until the minute hand turns enough revolutions to get to the correct hour would be a real pain. Imagine having to do that for the "Fall back" adjustment. You'd need to hold the button long enough for the minute hand to turn 11 revolutions. I believe you'd have to hold the button for a full 3 minutes for that. Stay away from this clock if you aren't able to receive the atomic radio signal.Tip:Be patient. If it doesn't seem like the clock is working correctly, don't pull the battery or hit reset to try it again. Just leave it on the wall and the clock will wait for the signal and adjust itself correctly.When I first inserted the battery and hung the clock up, it started moving the minute hand rapidly, and after about 3 minutes of turning, it came back to 12:00 and stayed there. I thought it wasn't working and hit reset, pulled the battery etc. Each time, the clock tried to adjust itself, but always came back to 12:00 and stopped. I decided to just leave the clock on the wall and after a couple of minutes, the clock received the signal and adjusted itself to the correct time.Update:Working into the night when all was quiet, I realized that the clock DOES make a ticking sound. To me, it doesn't detract from how I feel about the clock, but if you're sensitive about that, deduct one star.

Keeps time accurate and fits perfectly in remodeled laundry room

MAR 2025 UPDATE: The radio setting has never worked once in all the time I've had this clock. Still, it does keep time well and looks attractive. I do recommend the clock if you're willing to set the time manually -- but note that "falling back" from daylight savings will be tedious as you wait for it to advance through 11 hours of time. I can't recommend this if you are buying it for the automatic set function.I like this clock. It looks super great and seems to work well. Except one thing -- the auto set feature did not work. I gave it a couple days but it seems like it never acquired a signal. Mind you, this wasn't some room buried deep in the house -- it was in the bathroom with an exterior wall and window.Some are saying you need to hang it a certain way to get it to set -- but that's not a great solution. That means you aren't going to get the time sync and timezone change features of the WWV radio signal when it's finally moved to where you want it.My recommendation is: it's a good clock. Set it manually and hang it. If the auto-set feature works for you then fine, but don't assume it will work right. Maybe someday they'll do a version with a better antenna or RF amp so the auto-set function works well. At the very least, it would be nice if they added an LED to indicate whether or not it has acquired the WWV signal.

I love this clock because it's completely silent.When I first got it, it wasn't able to detect the WWVB signal but it was raining outside, and rain or weather in general can affect the radio signal that the clock needs to receive in order to set itself. But when I woke up the next day, I found that the clock must have set itself during the night

Nice smaller clock, I have mine above a white board with a silver aluminum trim so it looks nice as well. No need to deal with that daylight savings non-sense or power outages. Silent, light, accurate
