About your Linear Clock

The parts

  • The clock face is the long bar with the numbers on it.  There are angle hangers at each end that make it easy to hang level. 
  • The pointer moves along the clock face to indicate the time.  It’s connected to ...
  • … the “sled”,  the box that moves along the track behind the clock face, and holds ...
  • … an internal clock, powered by a watch battery.  It lasts for 8 years, and is accurate to 8 seconds/year.  The sled has two buttons and a screen so you can set the internal clock.

Hanging it

  • There’s probably a great spot for it in your house, over a door or window. 
  • Don’t put it too close to the ceiling, since you may need room to lift the sled up and over the clock face to recharge it. 
  • Use drywall anchors, or be sure you hit wood with the screws.  Some clocks are heavy. 
  • Leave the wide-headed screws sticking out about ¼” from the wall. Set the angle hangers on the screws. Make sure each hanger fits behind the lip of the screw head! Don’t let them just rest on top of the screw head - they might slip off.  Back the screws out from the wall a bit if necessary.
  • Move the clock slightly left or right to level it.

Setting it

  • Basically, don’t.  It’s already set to Eastern Time, and its internal clock, powered by a watch battery, will stay right for eight years or so even if the main battery needs a recharge.
  • But if you move to a new time zone or something, then:
  • Lift the sled up to take it off the clock face. 
  • Press either button. The screen will light up and show you the internal clock’s time. Hold the right- or left-hand buttons to change the time.  
  • When the time is set right, put the pointer back at the correct time on the clock face. Make sure the gears are on the track: it should resist you if you try to push it left or right. 

Reading it

  • We hope this is obvious. Except ...
  •  … at night, it moves backward (right to left) for six hours. At 6 AM, it starts over again. 
  • Some clocks have a glow-in-the-dark dot at every night-time hour, and on the pointer too.  At night you can see at a glance whether it’s between 3 and 4 AM, for example.  

Charging it

  • A fully charged battery will run the clock for 9 months or more.
  • If you find the pointer parked at 6AM, that means the battery is too low to function.
  • Lift the pointer and sled up and over the clock face, take it down, and plug it into any USB port overnight. 
  • If you want, you can press one of the buttons on the sled to check the battery level: 4 Volts or more is fully charged.  But don’t worry, you can’t overcharge it. 
  • In the morning, put it back so it indicates the right time on the clock face. Make sure the gears have grabbed the track: it should resist you if you try to push it left or right.

Telling us about it

  • Email
  • We’d like to hear why you love it.
  • We’d really like to hear if any little thing might be better! A hint is all we need, like maybe “Weird setting behavior”, or “Ugly font”.  If we don’t understand what you mean, we’ll email you back.


  • If it stops making you happy, do tell us why, please. See above. Maybe we can fix it.
  • If we can’t fix it, then you can send it back, in good condition, within the first 6 months, and we’ll refund your money.  (We ask that you pay the shipping costs.)
  • “No questions asked”? No, we’ll definitely ask you why you want to return it.  And we’ll thank you for your comments, too.  But we won’t quibble about your refund.
