What
you need to know about the accuracy of hours
The main and main function
of the watch is to display the exact time, and only then it is an addition to
the style, decoration, expensive accessory. Among the admirers of this
accessory there is an opinion that expensive and high-quality watches with
mechanical drive will always be more accurate than quartz ones. Is it really?
Should I buy quartz models, or should I prefer classical mechanics in pursuit
of jeweler precision? Let's try to sort out this issue.
Mechanical
clock mechanism
The statement that the
accuracy of the clock depends on the type of mechanism is correct. For example,
a mechanical watch, even the most expensive, has a slightly larger error than
quartz ones due to the peculiarities of the mechanism itself. The permissible
error in the course accuracy must be within the limits of “minus” 40 “plus” 60
seconds in one day. It depends entirely on the balance of the pendulum clock.
The pendulum itself, depending on the manufacturer, may differ in size, weight
and frequency of oscillations. The higher the last indicator (measured in
oscillations per second), the more accurate the indicator is the course of the
clock.
It should be understood that
in a mechanical clock, the mechanisms inside the case are in a tense state due
to the presence of a spring factory, therefore they should be treated with the
utmost care. Any blows, falls can negatively affect their work.
The
accuracy of the course of this type of clock can affect:
• ambient temperature;
• the location of the clock
in space;
• effects of vibrations and
vibrations;
• degree of wear and aging
of watch movements.
It should be remembered that
this parameter is also affected by their regular winding and excessive winding
of the crown. This is the case when "strongly" does not mean
reliably! Modern watches are mainly equipped with self-winding function, which
has a positive effect on the state of the mechanism, since the spring is in a
constant compressed state close to optimal.
Mechanical models are
assembled from many small parts, which are subject to high quality
requirements. To describe such accessories often use the concept of
chronometer. This is a special type of watch that has been certified in a
special laboratory. Provided the standard tests pass, the chronometer error
should not exceed “minus” 4 “plus” 6 seconds in one day. Naturally, certified
watches will have a higher value and status. But in the modern market and in
our product catalog, in particular, there are many models that have not been
subjected to this procedure, but have a sufficiently high accuracy.
Quartz
watch mechanism
The quartz mechanism is more
durable and reliable in comparison with the mechanical one. This is due to the
lack of a large number of parts and moving mechanisms. In this type of clock,
quartz is responsible for accuracy. In other words, it is a crystal that, under
the influence of an electric current flowing through it, gives in to a
pulsation with a high frequency. A special converter picks up these signals,
converts them into impulses that control the movement of arrows. For such hours
the admissible course error is within the range of “plus or minus” 20 seconds
per month. And this in turn is much less than that of mechanical accessories.
The
accuracy of the watch with a quartz movement depends on:
• on the frequency of the
crystal oscillator - the higher the frequency, the higher the accuracy.
However, increased energy consumption is considered a side effect;
• from temperature changes -
in freezing temperatures at temperatures less than minus 6 degrees, there is a
significant decrease in stroke accuracy;
• from moisture ingress into
the case; therefore, due attention should be paid to preventive inspections of
watches.
The work of quartz watches
is carried out from the battery power. This is one of the main advantages of
this type of watch, allowing them to work without interruption for more than
one year. Moreover, there are special types of batteries that can operate without
replacement for up to 10 years. This is largely achieved through the energy
optimization mechanisms implemented by the manufacturer. For reliable and
stable operation, it is recommended not to save on the battery and always use
only high-quality batteries when replacing. Cheap low-quality power supplies
have a very limited period of action, and may also oxidize, which in turn will
lead to loss of accuracy or final breakdown of the clock.
What is the most accurate watch?
• mechanical watches are
inferior in accuracy to quartz watches due to their specific mechanism design
and require periodic manual adjustment of time accuracy;
• mechanical watches can be
equipped with the function of automatic winding due to their design are more
accurate than mechanical watches with manual winding;
• The effect of ambient
temperature directly affects the accuracy of any watch.
