Time measurement
All wristwatches and clocks are used to measure the passing of time, the succession of hours. This is the miracle of these devices. They work with precision as truly metallic hearts. To measure we need a unit of measurement. For length we use the metre and for volume the litre, etc. To measure time it has been necessary to adopt a pattern. The earth´s rotation has provided us with one. The earth rotates once every 24 hours. But a solar day is not the same length in different seasons. Astronomers have calculated the average duration of a solar day and this has given us a unit of measurement: the 24-hour day or, more precisely, 86,400 seconds.

How watches measure time
The ancients recognized the need to measure time. The day was too big as a unit of measurement and they subdivided it into shorter periods. At first with sundials and then with hourglasses, etc. In our contemporary clocks, the pendulum has been replaced by the balance wheel.

The history of measuring time has always been characterized by the desire to become very precise.

Tuning fork and, later on, quartz watches are more precise than mechanical watches because they can divide the second into more parts.

Today, atomic clocks, with an error of just 1 second every 30,000 years, are a benchmark for precision.

The latest thing are some studies based on hydrogen´s properties that would achieve a precision of 1 second every 3 million years.

Kronos automatic watches
Kronos automatic watches are exclusive thanks to the precision afforded by their mechanism.

An automatic watch runs by taking advantage of the movement of the person wearing it. This turns the rotor and winds up the watch. The normal activity of one person is more than enough for the watch to work, even when it is taken off at night. It continues to work for approximately 40 hours when not being worn. To make the watch work again we need to wind it up. If it has a calendar, take care not to change the date when the hands of the watch are between 10 p.m. and 3 a.m, because you can damage the date mechanism.

An automatic watch doesn´t need batteries or electric circuits to work. It has clean energy and doesn´t produce contaminants. A mechanical watch is precise but not as much as a quartz watch. It is made for people who appreciate the legendary "tick tock" of its mechanism.

It is advisable to check the watch every 3 or 4 years to clean and lubricate its mechanism. If it´s water resistant, it´s advisable to check the watch´s seal every year.

Kronos quartz watches
Kronos quartz watches are produced with the best components from the watch industry. They have a battery that lasts at least one year. When the battery runs out, it should be replaced as soon as possible, if possible at a Kronos dealer. Violent knocks, strong magnetic forces or high temperatures can damage the watch´s mechanism.

Water resistance
Watches are water resistant if this is stated explicitly on the back of the watch. Water resistant and water resistant 3 ATM watches withstand rain and splashes but they can´t be submerged in water.

Watches can only be submerged from 5 ATM for swimming and from 20 ATM for diving. It´s advisable to check the watch´s seal every year. Before it comes into contact with water, check that the crown is in position (0) and, if it´s a screw crown, that it´s well screwed in. Never modify the crown´s position while the watch is wet. After contact with seawater it´s advisable to rinse the watch with fresh water.

To clean water resistant watches, use a fine brush, water and non-abrasive soap.

Instructions Kronos K300 automatic
This watch is designed to be submerged up to 300 metres.

It has an escape valve for release helium gas accumulated in the watch casing. Hermetic bells where divers take a break or begin the decompression period have oxygen and helium at a higher pressure than atmospheric pressure. Helium gas molecules are very small and can penetrate the watch casing. When it comes to the surface, the escape valve releases the helium gas accumulated for any differences in pressure.

How to operate the escape valve: The helium escape valve is in the screw crown located at 10 o´clock. During normal use and dives, the crown must be screwed in. It only needs to be unscrewed during decompression due to the pressure differences when the helium gas is released. On the surface, when we reach atmospheric pressure, the crown must be screwed in again.
