IKEA STOMMA / TROMMA Wall Clock $2.50 @ Ikea

711

IKEA introduces a new proper size (25cm) TROMMA wall clock, I can't find the link on Australian web site, so I pointed the link to Lithuania web site for your reference.

Both the STOMMA (20cm) and TROMMA (25cm) are sold at $2.50 each, and battery no included.

Product details

  • No disturbing ticking sounds since the clock has a silent quartz movement.
  • Highly accurate at keeping time as it is fitted with a quartz movement.
  • Batteries are sold separately; 1pc LR6 AA 1.5V required.
  • We recommend using alkaline batteries in the clock.

        I do found batterys die very quick on these clock, maybe every 3 months, eneloop only last like a week.

        • +3

          My STOMMA is the same, although I do find its batteries last a lot longer if I place the clock flat (horizontal). I've taken mine off the wall now and keep it on the floor, but this does make it even harder to read, not just because of the viewing angle but also because you don't know which way is up.

          • +4

            @iglot: If it's on the floor, there's only one way up 😉

            • +4

              @bargainparker:

              last a lot longer if I place the clock flat (horizontal).

              That's because the second hand isn't balanced, like the second hand in some clocks are. As the second hand sweeps from 6 o'clock to 12 o'clock, the clock's motor has to lift the weight of the second hand, and the motor is severely underpowered (to give a long battery life). When the battery gets half-flat, the motor can't lift the second hand.

              If you remove the second hand (it should just pull out), you'll get almost the same running time as when you were laying it flat. The motor still has to lift the minute hand and the hour hand, but as these move much slower, the motor has enough power for that.

              However, removing the second hand makes it much less obvious when the battery runs flat and the clock stops. Perhaps just cut the second hand much shorter, leaving it maybe 15mm long?

              • +2

                @Russ: Funny enough, looks like they removed the second hand from the Tromma

              • +1

                @Russ: I cut my second hand in half. Worked well.

                • +1

                  @MasterScythe: That cuts the motor load down to 1/4 of that required for the full second hand. Half the weight, and the centre of mass is half the distance from the hub.

                  If you want to go further, you could cut all of the hand off, and glue a clear plastic disk to the hub. Draw a line on the clear plastic disk, to function as the "second hand". I'm not sure what type of glue would work best, maybe silicone rubber would work well?

                  I don't have my STOMMA clock any more, I gave it to my Mum.

                @Russ: You should have replied to iglot 👍

                But, there is another way of making batteries last longer. Just send it to the gym, but not for too long, otherwise it's going to run like crazy.

        • +2

          Are you using Eneloop (standard) or Eneloop Pros? Those Eneloops aren't suitable for clocks because the power consumption is very low. The battery will self-discharge faster than it is being drained. Eneloop Lites are suitable.

          https://eneloop101.com/faq/#technical-faq
          Look under the "Eneloop Vs Eneloop PRO Vs Lite, What model do I need?" section.

          I have this clock and it's lasted for more than a year so far using a non-rechargable alkaline.

    • +1

      I bought three, one in a week and the other in two months with the problem of running out of battery quickly, but the other one is accurate in time and has no problem for more than a year. Looking at this, there seem to be a variety of cases in this clock.

      • +1

        Did you try 365 returns policy? https://www.ikea.com/au/en/customer-service/ikea-returns-and… on the problematic clocks?

        "You can return any product, even if you assembled it, as long as it's in unused and re-saleable condition. If the returns criteria are not fully met, we may refuse the
        return or offer an exchange or gift card."

        I've not (yet) had to return a clock before, but I do wonder, especially in your case the clocks are not all built the same.

        • I don't have any complaints about Ikea's refund policy because I've been refunded all the stopped wall clocks. However, it is regrettable that the wall clocks purchased on the same day have different quality.

    • Dead on arrival - wasn't even worth the fuel to return. Essentially the second hand swept wonderfully around the dial - but the minute and the hour hands refused to follow.

    No disturbing ticking sounds since the clock has a silent quartz movement.

    Very important.

    • Yes i have one too. I recommend it.

      • is it silent?
        i need a wall clock because they are aesthetically pleasing however the click noise is annoying.

        • No disturbing ticking sounds since the clock has a silent quartz movement.

          I think so.

        • +1

          No
          It doesn’t tick but you can hear it running

        • +8

          They are not completely silent. The "quartz movement" is completely silent, but it's also completely silent in normal battery-powered clocks that tick. The "quartz" part of these clocks is an electronic circuit, so of course it's silent. Almost every battery-powered clock has "Quartz" written on its face, referring to this.

          In a clock mechanism, there are four parts:

          • the oscillator, which can be a pendulum or an electronic "quartz crystal oscillator"

          • the escapement, which turns the oscillator output into rotary motion

          • the gears

          • the hands

          Generally, the movement is considered to be all of these parts except the hands.

          The difference between a standard battery-powered clock and this clock is that the escapement is a motor, which is silent. But the gears still make some noise, these clocks make a continous "whir-whir-whir-whir" noise, which is quieter than most "ticking" type mechanisms, but not completely silent. In the middle of the night, I can still hear this clock from across the room.

          When they say this clock has a "silent quartz movement", they are stretching the truth, because the quartz bit is only part of the movement. The rest of the movement isn't silent and isn't quartz.

          • +1

            @Russ: Perhaps these should be called lower dB clocks, than silent (literally)… then again it's "marketing" silent is easier to sell.

            I do hear some "whir" too, but not noticeable. Maybe it's not lubricated thoroughly in the motor/gears? I took apart a clock once as it was slowing down even with new batteries and I WD40'ed it LOL. It lasted for a while before eventually giving up…

            • +2

              @SF3: The problem is that to get a reasonable battery life, the motor has to be about as powerful as an ant, and any friction in the system will stop the motor. To keep the friction low, all of the gears are loose fitting, and that makes them noisy, they rattle on their shafts (stationary shafts on which the gears rotate). Lubricant really only helps when there is a tight fitting, I wouldn't expect it to work for this type of clock.

              I have the 20cm clock, and the slop (looseness) in the gears is quite visible: watch the second hand as it passes the 12 o'clock mark. Between 12 and 1 the second hand will appear to jump 2 seconds in one second, that's caused by the slop in the gearing. There is also a 1-second "pause" between 6pm and 7pm. In both cases it's caused by the weight of the second hand, which isn't balanced at all.

            • @SF3:

              I WD40'ed it LOL

              WD-40 isn't a lubricant. WD stands for "Water Displacing" - it is a solvent or rust dissolver. Any lubricant-like properties that you see with WD-40 come from whatever the WD-40 has dissolved.

              • @pjetson:

                WD-40 isn't a lubricant.

                You are correct that its main purpose is water displacement, but both Bunnings and Supercheap Auto describe it as a lubricant, and it does work as a lubricant.

                From Wikipedia, "In 2009, Wired published an article with the results of gas chromatography and mass spectrometry tests on WD-40, showing that the principal components were C9 to C14 alkanes and mineral oil."

                The WD-40 can, while not directly saying it is a lubricant, does say "stops squeaks".

              • @pjetson: I thought the same as you until recently.

        • If you are close to it, you can still hear it, but it is more like continuous soft clicks

    • yeah, very quiet, any the second hand move in sweeping motion just like high end automatic watch, that's why it's quiet.

          It's true, but I use it in my kid bedroom and as she's learning to tell the time, it's very hard not to see the numbers.

      The last deal this was posted, I went and bought one. Then took the front off, grabbed a sharpie and coloured the numbers in. Works a treat and clock still going strong.

      • Might have to do with mine. Been putting it off long enough.

  • As this suits to use in the kid's room, I wish they come with different colour background and/or the numbers.

  • +1

    I can confirm its a super quiet mechanism. Inaudible unless your ear is pressed against it.

    The mechanism can easily be removed. A cheap way to upgrade a noisy clock.

    • thanks sir off to ikea i go tomorrow.

      • +1

        Be careful, I tried upgrading an old clock with a new mechanism (not this one) and the hands of the old clock wouldn't fit the shaft of the new clock mechanism. Had to use the hands from the new clock mechanism as well, which weren't the same and didn't look quite right in the old clock.

        Fortunately the new hands were the right length, measure your clock's hands and check at Ikea before buying. Putting hands from a 25cm clock into a (maybe) 40cm clock will look odd.

        • +1

          Yeah, a short hand and a shorter hand :)

  • Great minimalistic aesthetic.

    • I drew a circle on my wall and use the amount of sunlight in it too work out what part of the day or night it is.

      I like minimalistic aesthetic

      • Reminds me of this.

      • You mean on your spaceflight wall?

    Budget $2.50 for the wall clock and $77.95 for hiking supplies to get through the Ikea maze.

    • No soft serve or hotdog at the end?

      • +3

        You start with the hotdogs so you have supplies to get you through

        • Clever. I find it easier to walk against the flow too….. Enter through the exit, particularly if I'm not looking at furniture.

      hearing all those bad IKEA puns is going to TROMMAtise me

  • It looks like it has a smooth sweep like an automatic watch.

    • +6

      An automatic watch doesn't actually have a smooth sweep. In such a watch, typically the (rotary) pendulum goes back-and-forth four times a second, and the second hand moves a quarter of a second for each back-and-forth. The motion of the second hand is rapid very small steps, which is why it appears to move smoothly.

      If you put the watch to your ear in a quiet room, you'll probably be able to hear the four (or so) ticks per second.

  • Why no online

  • +1

    It's $2.50 with a modern look clock (most low price clocks looks poorly IMO). I have the 20cm (smaller one). In the long run battery running cost could get higher than the clock :D

    • How long do the batteries last on yours?

      • gosh - maybe many months if not a year, I think I may have changed it once (long enough not to remember :p)… I probably jinx it now :D

      • I was using eneloops on mine, until I gave it away. I vaguely recall an AA eneloop lasting three months.

  • +1

    It’s about time

  • thanks been waiting for this one to come down in price for a while.

  • +8

    This is not a deal because it is the regular price of this clock, it has always been 2.49! ever since it was introduced a few years ago. This was on the last two annual IKEA catalogues (valid for the entire year)

  • Try going into the Check Out, suddenly there is a Service Fee of $5.00 so if you say bought 2 clocks to check out its $10.00

    I am uncertain if this is silent, as the true silent clocks should say, Continuous Sweep Movement, or Continual Motion.

    Ahh well, had there been an Ikea on the Gold Coast I may have considered. Not going to drive half way to Brisbane to buy a clock.

    • It is a continuous sweep motion. The motor mostly works as a flywheel, and from the (quiet) sound it makes, it sounds like power is being pulsed to the motor four or five times a second.

      But because it's battery powered and the motor has a very low power output, friction is a major concern, and the gears are very loose on their shafts. You can hear the gears going "Whir-Whir-Whir-Whir" as they speed up and slow down, several times a second.

      This clock isn't as quiet as mains-powered continuous sweep clocks are.

      • Yes you’re right, during the day its not noticeable but on a quiet night you can hear its gear. But we’re talking about a $2 clock so I doubt people here will have a high expectation. Like I said, its great for kids room.

  • +1

    Its a trap..

  • no problems with batteries here.

    good art project this is

  • +5

    why the heck is this front page, this has been regular price since last year? this isn't a sale, its regular price, lmao.

  • I have this. It keeps surprisingly good time. https://imgur.com/a/0tiyZwe

  • does it go click click at night?

    • +1

      On a quiet night, you can hear gears running rapidly tuk tuk tuk, but it's very soft.

    • No click click at night. During the day you could say it's completely silent. At night, after all the background noises are completely gone, you can hear it running a bit - but it's less noisy and not as disturbing as ticking clocks.
      TBH just buy one and if you don't like give it away, it's only $2.50

  • +3
    • That's really good. How did you achieve such even colouration? It doesn't look like you used a permanent marker, did you use paint?

      • +2

        I used permanent marker (Sharpie) but had to colour it twice to make it more even.
