La Crosse Technology WT-3102B 10-Inch Atomic Analog Clock
Category: Decorating & Remodelling



I own 8 atomic clocks 5 of which are these LaCrosse brand clocks. Unfortunately, the only problems I’ve experienced are with the LaCrosse. The others have been problem free. Although I am very close to the Colorado transmitting station (Utah), some of my LaCrosse clocks have had a hard time picking up the atomic signal. I’d wake up in the morning or come home from work in the evening and notice several clocks were WAY off the correct time. (Sigh) I’ve had to reposition the clocks several times and ended up locating them in areas I really didn’t want them. But I finally got all of the LaCrosse clocks to work at least.
Some of the LaCrosse clocks tick loud enough to disrupt sleeping. Others don’t which is odd because they are all the SAME model. I’ve had to rotate clocks around until I found one quiet enough to put in my bedroom. But the quiet one has a signal receiving problem, so I had to put it on a different wall and move the artwork to a different place. It looks rather awkward now. (Sigh)
Of the eight atomic clocks I own, five didn’t update at daylight savings time. You guessed it! All five were the LaCrosse clocks. (Sigh) The other three updated instantly. This was one of the main reasons I got the atomic clocks to begin with. I didn’t want to hassle with updating the clocks manually. When I contacted LaCrosse support, I was told that it would take up to five days for the new time to register. Why LaCrosse clocks take five days while the other brand atomic clocks updated instantly is a mystery to me. It defeats the whole purpose of having the atomic clocks in the first place. I’ve inserted a new battery and reset the clock and waited a day or so with no DST update. I finally got tired of it and put them on a different time zone so they would reflect the correct time. Waiting almost a week for the clocks to update is ridiculous!
Overall, I’m rather disappointed. I’ve actually spent MORE time adjusting and tuning and moving the LaCrosse atomic clocks than I ever did with my old manual ones. LaCrosse brags about its “technology”, yet I find it hugely lacking. I am amazed at the good reviews here. In fact, I bought all these clocks based upon them. I also gave several as gifts around Christmas time (I’m so sorry for those of you who got one from me).
I would certainly recommend another brand.
UPDATE 3/17/07: I contacted LaCrosse customer service and was told there was a “flaw” discovered in the engineering of this model which doesn’t allow them to update the new DST. They claim they were just as “surprised” about this as their customers. They took my information and promised to arrange an “exchange” of clocks some time in April 2007. I hope they don’t expect me to pay for shipping them. I own five of these models. I will update again in April when I get further information. Meantime, I changed the “time zone” to reflect the correct time. Luckily, I’m able to do that.

I purchased this clock which is advertised as Model # WT-3102B. The clock that I received is Model # WT-3102. I do not know what the difference is between the two model numbers but my clock does not work properly with the new daylight saving time rules. I tried to call LaCrosse technical support and the line has been busy for several days. When I finally got through the most you can do is leave a message in voice mail for them to call you back and they have not called me back. Although LaCrosse advetises that all of their clocks are compatible with the new daylight saving time rules, this clock is not. Based on this and the lack of technical support I cannot recommend this clock.

I bought 4 of these recently, and found that while they picked up the timing signal perfectly from WWVB in Ft. Collins, CO, they did NOT ‘spring forward’ for DST. Since the DST indicator bit is part of the time-code signal, this was very confusing. I just got off the phone with LaCrosse technical support, and they acknowledged that this is a known-issue (just confirmed in the last couple days), and the WWVB receiver IC used in any of the movements with a red sticker on the back IGNORES the DST bit sent on WWVB (and uses the pre-2007 DST date algorithm instead.) LaCrosse is taking names and numbers and will supposedly be contacting everyone in late April with instruction on how to exchange the product for a working one.

Wow, This is a nice little Atomic clock. At 10 inches in diameter with the face measuring 7 and 1/4 inches, It’s perfect for a small room. The numbers are on the thin side so I wouldn’t recommend this clock being placed where you had to view it from a great distance. The case is plastic but I was surprised that the face plate was glass! Pretty nice for the $12.99 I paid. When you set the clock up you just put in the battery and press the time zone, That’s it! The second hand ticks a few beats and stops. This is normal. A bit vague in the instructions, So don’t panic thinking it doesn’t work when none of hands move. When it finds a signal it moves and fast fowards to the correct time. My clock picked up a signal pretty quickly (about 2 hours before my digital wall clock normally does) so the reception is pretty awesome on the unit. The second hand is very quiet as it “ticks” every second so it wont keep you up at night like some noisy clocks I’ve had. A very nice little clock at a nice little price.

I have this model and the bigger silver WT-3144P that amazon always has as a buy it together option. It has been 5 days and no matter how many times I take out the battery and try pressing different buttons, they are both still 1 hour behind. I am starting to believe this clock will only be accurate in November when DST changes again. My 6 casio radio controlled watches all changed to the correct time on March 11th so the problem is not because of the signal coming into my house.
Since I am on the east coast, I can’t trick it into the correct time by using another time zone. This product has poor engineering and I don’t know if LaCrosse can come up with a fix.
