• One electronic controller runs up to 10 clocks – all accurately synchronized.
• Inexpensive quartz clock movements are easily modified for fast-time operation. Standard-size movements snap into most commercial clocks or can be installed on any clock using the included nut and washer on the threaded shank.
• Switch-selectable fast-time speeds from 1:1 to 15:1. Choose the best speed for your railroad.
• Simple but powerful output circuitry. Two outputs can each power five clocks along a 2-wire cable up to 75 feet long.
• Two cables give you 10 clocks over a 150-foot span - great for clubs!
• Run/Stop switch starts and stops all clocks at once.
• Fast Forward switch advances the clocks during an operating session.
• Reset switch quickly advances the clocks to the starting time, ready for the next operating session.
• Easy to build. A microprocessor replaces many components.

What to Order

You need one controller to run as many as 10 clocks. and one modified movement for each clock. Order the controller as a kit that you solder together, or already assembled and tested.

Order movement kits with parts needed to modify them for fast-time (including a set of hands), or order modified and tested movements. (with a set of hands).

Order the items you want by clicking the Add To Cart buttons on this page. To buy more than one of an item, change the quantity in the shopping cart, and click Update.

Fast Clock Controller

Movements and Hands

The secret to this fast clock is replacing a clock's original movement with a modified Klockit Q-80 movement, and operating it with an electronic controller. The modification takes about 15 minutes, and is fully described and illustrated in the controller assembly instructions (1.9MB PDF).

Because the Q-80 movement is a standard size, you can convert almost any clock into a fast clock. Usually the movement just snaps in! Or you can install it on any clock with the included nut and washer on the threaded shank. Use a clock already on hand, choose from the dozens available in stores, or build a kit from Klockit.

You need one movement for each clock on your layout.

Please note! The dial can be as large as 7" in diameter. You may be tempted to use a larger dial and longer hands, but this is not recommended because the Q-80 movement isn't powerful enough to overcome the inertia of long hands. It may be possible to achieve reliable operation with larger clocks by fiddling with the resistor added to the movement, or trying to balance the minute hand, but don't say I didn't warn you.

Buy your clock first so you can measure the dial thickness when ordering a Q-80 movement. Measure the thickness of the clock dial ("B" in this drawing). Order a movement that accomodates this thickness. For example, if your dial is between 3/16" and ¼" thick, order a ¼" movement. If the dial is 1/8" or thinner, order the 1/8" movement.

I offer Premium Q-80 movements and the resistors and wire to modify them for fast time, and also sell movements already modified and tested. You get one set of hands with each movement. You get the #66927 hands for clock dials up to 7" in diameter unless you choose a different set. See Clock Hands below for details.

Order this modified movement if you don't want to tackle the modification yourself. Includes one modified and tested Premium Q-80 movement and one set of hands. Select your clock's dial thickness from the drop-down list. To buy more than one movement, change the quantity in the shopping cart, and click Update..

This is a photo of the four available hand sizes and styles, along with rulers to help judge the actual length. You can snip off a short portion of the minute hand if it is too long.

If you prefer hands other than the #66927, select from the Choose alternate clock hands list and click Add To Cart. (There is a 1¢ charge for alternate hands because the shopping cart doesn't allow items with no price.) You may choose one alternate set of hands for each movement you order. To choose the same alternate hands for multiple movements, change the quantity in the shopping cart, and click Update.

Please do not order more hands than movements. Contact me for pricing if you need extra hands.
