• 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 buttons on this page. To buy more than one of an item, change the quantity in the shopping cart.

Fast Clock Controller

The fast clock controller runs up to 10 clocks fitted with quartz clock movements modified for fast-time operation.

	Fast clock controller kit – $55.00 This kit includes the circuit board and all electronics parts. You provide switches, power supply, and a case, if one is desired. Note: This photo shows only a representative assortment of parts, not everything that comes in the kit. Assembly instructions are in the online User Manual (2.1MB PDF, right-click, save... so you'll have a copy for ready reference). All switches are optional; with no switches connected, the clock starts running as soon as power is applied. You might choose to add a run/stop switch to stop the clock, and a reset pushbutton to quickly run the clock around to where it started, ready to go for the next operating session. Also, many people don't use a case. Instead they screw the circuit board to the layout benchwork, and install the fast clock switches in an existing control panel or on the layout fascia.
	Assembled fast clock controller – $90.00 Everything in the kit above, but assembled and tested. Again, you provide switches, power supply, and a case if one is desired. Even though the fast controller is assembled, you'll still want a copy of the User Manual (2.1MB PDF, right-click, save...) so you know how to use it.

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 the electronic controller. Modifying a movement takes 15-20 minutes, and is fully described and illustrated in the User Manual.

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 modified movement for each clock on your layout.

Please note! The dial can be as large as 7" in diameter. You might be tempted to use a larger dial and longer hands, but this is not a good idea 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 before ordering a Q-80 movement. Measure the thickness of the clock dial ("B" in this drawing), then order a movement that matches this thickness.

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. Each movement (unmodified or modified) includes one set of hands. 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.

This is a photo of the four hand sizes and styles available, 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 the button below it. (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.

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