Quartz Clock Movements

p0204 clock_assembly_5

We market genuine, top quality Takane quartz clock movements equipped with an on/off switch and mechanism advance wheel. (Note there are cheaper clones available which do not have these features which are very useful for setting hands and maintenance operations such as cleaning).

 

These movements can be used in numerous projects with clock faces made from many different materials. Popular choices include old LP records, hub caps and pottery and crockery pieces, the choice is basically yours, all you need to be able to do is establish the correct shaft length of your movement to suit the clock body, drill a 8mm central hole (shaft diameters are a standard 8mm) and find somewhere to hang it!

 

The Takane movements will serve as a replacement movement for numerous commercially made clocks where the movement has reached the end of its service life. For this end we offer purchase options without hands and numerals. Note that we will supply an average set of hands and numerals for customers who purchase a movement WITH hands and numerals and who omit to specify their preference. If you want your choice of hands and numerals please order them when you order your movement(s).

 

SEE HERE - We now offer High Torque clock mechanisms capable of driving hands suited to large clocks up to a metre in diameter!

 

Decisions

1. Decide on the optimum shaft length which is determined by the thickness of the clock face. You should allow a minimum of 2mm of protruding threaded shaft to fit the main mechanism mounting nut so an 8mm shaft is appropriate to a 6mm thick face, a 15mm shaft is good for 12 or 13mm thick face and a 23mm shaft would suit clock faces made from material around 20mm thick. If you have an excess of shaft then a packing made of something like stiff cardboard can be used instead of the black rubber washer supplied in the mounting kit with every movement.

2. Decide whether you need hands, numerals and second hand. (For mechanism replacement these may well replace a deceased Takane mechanism but other brands may use different hand attachment).

3. If you opt not to use a second hand you have the option of a brass shaft cap.

4. Do you need a hanger?

Hands

Hands are measured from the centre of the hole to the tip of the minute hand.

We supply 30 different hand options in several lengths.

Numerals

We offer self adhesive black or gold numerals in several sizes in either Arabic or Roman styles.

Check Contents

Refer to the parts diagram above.

All mechanisms are supplied with a set of mounting hardware - 1 each of plastic black cushion washer, brass washer, larger shaft nut and smaller brass second hand nut.

Before opening the inner plastic bag with the hardware check that contents are complete! It is very easy to misplace small items.

Optional Components

Note that the hanger and the shaft cap (used in lieu of a hand nut and second hand) are optional purchases. Replacement or additional mounting kit sets are also available.

 

Assembly

Clock movements require a 2A battery (not supplied) and assembly is simple. Refer to the exploed parts diagram above. If ordered with the kit, fit the hanger (which can be omitted if desired) against the clock body, then slide on the rubber washer and insert the clock body, hanger and rubber washer into the back of the clock face (into which you may have made a suitable rear recess).

 

At the front, slide on the brass washer and then fit and gently tighten up the mounting nut. DO NOT over tighten the mounting nut as this may damage the movement. The hour hand is pressure fitted next followed by the minute hand which has registration flats so take care here to correctly engage the flats on the hand to the matching flats on the mechanism shaft.

 

If your project is using a second sweep hand, fit the hand nut next to secure the minute hand (this needs a delicate touch to prevent cross threading) and then wait before press fitting the second hand until Initial Hands Adjustment below. This will allow the second hand to step right on 12 o'clock.

 

If you have chosen to omit the second sweep hand and opted for the brass shaft cap then fit this brass shaft cap instead of both the second hand and hand nut. 

 

Initial Hands Adjustment

With clock switched OFF, use the mechanism advance wheel and manually rotate the minute hand clockwise (of course!) to 12 o'clock, then gently force the hour hand (which is a friction fit and does not have a keyed shaft) also to 12 o'clock. Finally now press in the second hand also at 12 o'clock and switch clock ON.

 

Setting the Time

It is best practice to switch the clock OFF, adjust the clock to the right time by using the advance wheel on the back (best not to use your finger to wind the minute hand manually) and then switch the clock on.

 

Recessing

The quartz movement is 55mm square and 75mm across the diagonals which will need, if your design requires, a circular recess of 75mm diameter. You can of course drill a grid of overlapping holes in materials such as wood using a somewhat smaller forstner type bit than 75mm to avoid the expense of a 75mm forstner style bit. A square recess needs to be 56mm x 56mm. The recess should be at least 16mm deep to fully house the movement. If you use a hanger make the recess 16 to 17mm deep.

 

Extra Large Clocks

Note that these mechanisms will work fine with the hand lengths and offered. They are NOT intended for use with larger, heavier or extended hand sets.
