The question indicates a basic lack of clock mechanism or electronics knowledge. A quartz clock *can* be horridly IN-accurate if the rest of the mechanism of off kilter. Quartz crystals are used to count time due to their consistent frequency of vibration. And it is a safe and inexpensive application of technology. Radioactive atomic clocks are also used, but you don't want one on your wrist or in your house. - side note: most smoke detectors have a tiny radioactive "source" in them
You would have to know (a) what you are actually supposed to calculate, and (b) what ARE you given, not just what you AREN'T given. If no data is known, you'll have to do some measurements.
Quartz crystals, when properly sized, oscillate (vibrate) at fixed frequencies. These frequencies are not affected by temperature variations, other vibrations, radio waves, etc.A small quartz crystal will oscillate at 32,768 hertz (cycles per second) given a low amount of power (like that of a watch battery).Since the number 32,768 is a power of 2, and can easily be counted by a digital counter, the quartz crystal oscillator is a perfect match for use in a digital watch. Simply put, each time the crystal oscillates, the circuitry in the watch increments a 15-bit binary digital counter. Once the counter resets to 0, one second has passed.
An automatic is a completely mechanical watch, the wearer's movement winds the spring in the watch which then powers the watch, whereas a kinetic uses the movement to add charge to a battery contained within the quartz movement of the watch. Both systems essentially use movements transfered to power the watch through weights which move in the watch. A kinetic watch is likely to be more accurate than an automatic as it uses a quartz movement, although many modern automatic movements are very accurate to +/- 10 seconds per 24hrs or less. If you do not use an automatic watch for more than 36-48 hrs the movement will usually have stopped as the energy contained within the spring is likely to have been drained over this point, and will then need to be worn / given a gentle shake to get the watch moving again, so you would have to reset the time / date at this point. Some automatic watches now show how much 'power' they have remaining on their face. An automatic watch is likely to require more regular servicing than a kinetic or quartz watch as there are more moving parts.
The clock is one of the oldest human inventions , meeting the need to consistently measure intervals of time shorter than the natural units of the day, lunar month and the yearThe first major advance in clock construction occurred in Europe during the 14th century when the first mechanical clock ever made was created by one Henry de Vick r King Charles V of France Spring-driven clocks appeared during the 1400s, although they are often erroneously credited to Nurnburg watchmaker Peter Heinlin(or Henle, or Hele) around 1511. The earliest existing spring driven clock is the chamber clock given to Peter the Good, Duke of Burgundy, around 1430, now in the German Isches National Museum. The first record of a minute hand on a clock is 1475

Amethyst is a violet form of quartz.
Theoretically yes, though any given sample of quartz may contain inclusions (non-quartz stuff trapped inside) making it heterogeneous.
Usually you are given a card or number both sometimes to clock in and clock out of work you simply slide the card given or punch in the number your are given which is usually your work number authorized so remember it . You will see your log press your position you work and you are set the number of hours or time you clock in will be printed out instantly.
The given description fits to that of a clock.

The principal special property of quartz is that it is piezo-electric. That is if you apply a voltage to two opposing faces, the crystal will change shape; and vice versa. This is the device that in your phone/alarm clock/microwave that goes peep peep peep. Small pieces of quartz are shaped so that they operate (vibrate) at your target frequency, be it for a watch alarm, or a GPS receiver. Other materials may also be used for this purpose, but quartz is easily fabricated. p.s. Your bones are also piezoelectric, and the electrical signals given out by the stresses put on the bone, will aid in shaping the bone to best respond to that stress. Very clever!
Millimeters are smaller so if a measurement is given in mm it is likely to be more accurate than a measurement given in cm. However, it's important to note that neither mm nor cm is inherently more accurate.

Strictly speaking, Big Ben is a bell, not a clock, but given that the name is usually associated with the clock, the answer is yes, it is the tallest tower-clock, although there may be others that are higher off the ground!

Amethyst is the name given to the purple variety of quartz. Amethyst hence only comes in purple.
