Choose clock hands based on the size of your clock dial you are working with. So a little less than half the diameter of your clock face is standard. The length of your clock hands determines whether you need a standard clock motor or high torque (higher power) clock motor.
How do I know what size clock mechanism I need?
The post mounting hole of your clock dial (or mounting material) needs to have a large enough diameter to fit the shaft of the clock movement through it. The easiest and most accurate way to measure the shaft length on a clock movement is to use the depth gauge on a digital caliper.
Are clock mechanisms a standard size?
There are generally 4-6 basic sizes of movement available and your movement will generally fall into one of the sizes available between 9-31mm in length, if you movement is an odd measurement then the way round it is to simply go for the longer length shaft thats as close to your required measurement and put a spacer.
What is a clock shaft length?
The overall measurement of the hand shaft (B) is important when you are using a glass front on your clock. You must allow sufficient clearance in order for the hands to operate properly. The overall length is measured from the tip of the hand shaft to the case of the movement (B).
How do you identify clock movements?
The first set of numbers (six or eight with a hyphen in the middle) tell us what type of the movement it is and any additional number identify the length of the gearing (pendulum). Please note that Hermle clock movements often have the name of the clock case maker stamped onto the brass plate of the movement.
Are clock hands universal?
Lots of people think whatever clock hands they have will fit a new clock movement. This is not usually true. The mounting holes are not well standardized. So, if you already have the clock hands, you can just choose a similar length and style from us.
What is the diameter of a clock?
Option Two: FRAMED CLOCKS DIAMETER OF UNFRAMED Wall Clocks: 12 inch clocks are 12 inches diameter, 18 are 18 inches diameter, 24 clocks are 24 inches diameter etc! Make sure to get a battery that is over 1.3v for the large wall clocks. The larger hands take a lot of energy so a better battery will last longer.
How do you insert a clock?
Put a clock on your Home screen Touch and hold any empty section of a Home screen. At the bottom of the screen, tap Widgets. Touch and hold a clock widget. You’ll see images of your Home screens. Slide the clock to a Home screen.
What is the bezel of a clock?
The glass clock bezel & dials are a combination unit that starts with a heavy gauge steel face plate that can be mounted to your clock face with nails or screws. The holes are predrilled for mounting as well as the hole for your clock movement.
What is clock dial thickness?
Dial thickness is the measurement of the material that the shaft of the clock motor is going through. Example you have a piece of material which is 8mm thick you would simply choose a 10mm dial thickness size as the 6mm dial thickness would be to small and the 10mm is suitable for sizes up to 10mm.
How does a quartz clock measure time?
Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. Generally, some form of digital logic counts the cycles of this signal and provides a numerical time display, usually in units of hours, minutes, and seconds.
What does high torque mean for clock mechanism?
High Torque Quartz Clock Movements are geared special on the inside of the unit stronger as to take more weight. This means the movement is just mounted to the dial and nothing else, then you can put you’re hour hand on, and then the minute hand with its nut.
What is Euroshaft clock movement?
A euroshaft movement has shaft measurements as follows: Hour pipe 5.0mm, Minute pipe 3.5 x 2.8mm, Generally speaking the majority of German quartz movements will have this fitting as is easily spotted from the roundshaft variety Germany also produces from the small threaded shaft which holds the minute hand in place.
What do the numbers on a clock movement mean?
The movement number usually tells us the way the clock chimes, the location of the chime hammers, if it’s weight or spring driven and much more. When the movement number is known, a replacement can be ordered and it will be the same movement as the old one.
How long do clock movements last?
On average, a clock movement lasts for approximately 10 – 15 years, though often these movements can be faulty and need replacing much earlier than this.
How do you measure the diameter of a clock?
Measure Your Clock The very first step in determining clock hand size is to measure the diameter of your clock face, also known as a clock dial. Use a ruler to measure the outside diameter of the time ring. If there is no time ring, measure the outside edge of the numbers or markers.
What’s the big hand on the clock?
The large hand on a clock that points to the minutes. It goes once around the clock every 60 minutes (one hour). Example: in the clock on the left, the minute hand is just past the “4”, and if you count the little marks from “12” it shows that it is 22 minutes past the hour.
What hand goes on clock first?
How are the clock hands mounted? As a first step, insert by pressing the hour hand on the h 12, until you reach the stop with the thread. Afterwards, always insert the minute hand on the h 12 until the stop is reached. Finally insert the second hand into the fulcrum of the shaft.
What are the hands on a clock called?
hour hand. the thing that points to the hour on a clock or watch. The thing that points to the minute is called the minute hand, and the thing that points to the seconds is called the second hand.
