18 Questions & Answers About Wristwatches!

We answer the most relevant questions about wristwatches. A watchmaker has various ways to test a watch for water resistance:

1. Wet test:

Procedure: In a chamber half filled with water, excess pressure is created. The watch is immersed from the air-filled half into the water while the pressure is slowly reduced at the same time. Indicator of leakage: If the watch is leaking, the air is forced outward through the leak, and air bubbles emerge at the leaking point. Risk: High risk, especially if the watch is leaking.

1. Dry test:

Procedure: Excess pressure is created in a chamber. A sensor measures whether the volume of the case changes. This only happens with sealed watches, because the excess pressure in the chamber creates negative pressure inside the watch and the crystal and case back deform minimally. Indicator of leakage: In a leaking watch, the internal pressure equalizes and no change in volume occurs. Risk: Virtually no risk for the watch being tested.

1. Condensation test:

Procedure: The watch is placed in a container of water for 30-60 minutes. The watch is then heated and cooled rapidly with cold water. Indicator of leakage: If water condenses behind the crystal, the watch is not water-resistant. Risk: Very high risk, especially with leaking watches. An overhaul includes numerous steps to ensure a watch's functionality and longevity:

• Checking the case and strap
• Removing the movement
• Checking the winding mechanism
• Checking the escapement function
• Checking the motion works and calendar mechanism
• Completely disassembling the movement into its individual parts (at least 40 parts in simple hand-wound movements, approx. 70 parts in automatic watches with date, often over 100 parts in chronographs)
• Replacing defective movement parts

The difference between "waterproof" and "water resistant" refers to the degree of protection against water:

1. Waterproof (Wasserdicht):

A waterproof product does not let any water through at all. It is completely sealed against water ingress and offers maximum protection, even during prolonged submersion in water.

1. Water Resistant (Water-repellent):

A water-resistant product offers a certain degree of protection against water, but it is not completely impermeable. It can resist water to a certain extent, such as in rain or splashes, but it is not suitable for full submersion in water. [/et_pb_accordion_item][et_pb_accordion_item title="4. What do the ATM ratings on watches mean?" _builder_version="4.24.3" _module_preset="default" global_colors_info="{}" open="off"] The ATM ratings on watches refer to the watch's water resistance and stand for "atmospheres." One atmosphere (ATM) corresponds to the pressure at a water depth of 10 meters. Here is an overview of the common ATM ratings and what they mean:

1. 3 ATM (30 meters / 100 feet):
   • Suitable for everyday exposure to splashes, such as rain, washing hands, and accidental splashing.
   • Not suitable for swimming or immersion in water.
2. 5 ATM (50 meters / 165 feet):
   • Suitable for showering, bathing, and shallow swimming.
   • Not suitable for water sports, diving, or high-pressure water.
3. 10 ATM (100 meters / 330 feet):
   • Suitable for swimming, snorkeling, and other water sports at shallow depths.
   • Not suitable for scuba diving.
4. 20 ATM (200 meters / 660 feet):
   • Suitable for open-water swimming, snorkeling, and scuba diving at moderate depths.
   • Offers good protection for most underwater activities, except extreme deep-sea diving.
5. 100 ATM (1000 meters / 3280 feet) and higher:
   • Suitable for all types of diving, including deeper scuba diving.
   • Offers the highest protection against water ingress under extreme pressure conditions.

Important notes:

• These ratings are based on laboratory conditions and static pressure. Actual water resistance can be affected by factors such as temperature changes, movement in the water, and aging of the seals.
• Regular maintenance and inspection of the seals are important to ensure water resistance.

The helium valve on dive watches is a special device developed to solve the problem of helium buildup inside the watch during deep and long dives, especially saturation dives. Here are the main functions and background of the helium valve: Function and background

1. Helium accumulation in the watch:
   • During saturation dives, in which divers work in pressure chambers for extended periods and breathe helium-oxygen mixtures, helium can enter the watch through tiny openings and seals. Helium has very small molecules that can penetrate even the best seals.
2. Pressure difference:
   • During ascent and the decompression phase, the pressure inside the watch can be higher than the ambient pressure due to the accumulated helium. If the pressure cannot equalize, this can cause the crystal to pop off or the watch to be damaged.
3. Helium valve:
   • The helium valve is a safety mechanism specifically designed to allow pressure equalization and protect the watch.
   • There are two types of helium valves:
4. • Automatic helium valve: Opens automatically when the internal pressure of the watch exceeds a certain threshold.
   • Manual helium valve: Must be opened manually by the diver before surfacing to release the pressure.

Advantages of the helium valve

• Protection against damage: Prevents the crystal from popping off due to pressure differences or the watch from being damaged in other ways.
• Increased reliability: Ensures that the watch continues to function reliably even after long saturation dives.
• Professional use: Makes the watch suitable for professional use in saturation diving and pressure chambers.

When is a helium valve necessary?

• Professional diving: A helium valve is especially important for professional divers carrying out saturation dives and working for extended periods in pressure chambers with helium-oxygen mixtures.
• Recreational diving: For recreational divers who dive at shallower depths and use normal breathing air, a helium valve is generally not necessary, as no significant helium buildup occurs inside the watch.

Conclusion The helium valve is a specialized feature that ensures the integrity and functionality of dive watches during and after extreme diving conditions. It is an essential feature for professional divers working in environments where helium plays a role, but it offers no significant benefit for the average recreational diver. 12. What is a tachymeter scale? A tachymeter scale is a scale placed on the dial or bezel of a watch that is used to measure speed based on elapsed time. This feature is particularly useful on chronographs, i.e. watches with a stopwatch function. Here is a detailed explanation of how a tachymeter scale works and how it is used: How the tachymeter scale works

1. Basic principle:
   • A tachymeter scale measures speed over a known distance by using the elapsed time.
   • The scale is calibrated to display speed in units such as kilometers per hour (km/h) or miles per hour (mph), based on the time needed to cover a fixed distance.
2. Typical calibration:
   • The scale on a tachymeter watch usually begins at around 500 units and ends at around 60 units. These numbers represent speed.
   • The calibration is based on the formula: Tachymeter scale = 3600 / elapsed time in seconds, where 3600 is the number of seconds in an hour.

Using the tachymeter scale

1. Measuring speed:
   • Start when you begin covering a known distance (e.g. 1 kilometer or 1 mile).
   • Press the chronograph start button when you pass the starting point of the distance.
   • Press the stop button when you reach the end of the distance.
   • The position of the chronograph hand on the tachymeter scale indicates the average speed over that distance.

Example: If you cover 1 kilometer in 30 seconds, the chronograph hand on the scale will indicate about 120 km/h.

1. Other applications:
   • Production rate: You can also measure the production rate by timing how long it takes to produce a certain number of units.
   • Event frequency: Any repeatable activity completed within one minute can be measured with a tachymeter.

Limitations

• Minimum and maximum speed: A tachymeter cannot measure speeds below 60 units per hour (one unit per minute) or above 500 units per hour.
• Known distance: Using a tachymeter requires that the distance over which the time is measured is known precisely.

Conclusion The tachymeter scale is a useful tool for measuring speed and frequency over a known distance or time period. It is particularly useful in situations where the speed of an object or the rate of a process must be determined quickly and accurately, and it is used in fields such as motorsport, aviation, and industrial processes. 13. What do magnetic fields do to watches? Magnetic fields can cause various problems in mechanical and electronic watches, especially in mechanical movements. Here are the main effects of magnetic fields on watches: Mechanical watches

1. Stopping or slowing of the movement:
   • Magnetic fields can affect the sensitive metal parts in the movement, especially the balance wheel, spring, and other moving parts.
   • This often causes the watch either to run more slowly or even stop completely, depending on the strength of the magnetic field and the susceptibility of the movement.
2. Rate deviations:
   • Magnetic influences can lead to irregular timekeeping behavior, where the watch does not keep accurate time.
   • This can cause the watch to gain time quickly or run more slowly, affecting its accuracy.
3. Damage to the watch:
   • Long-term exposure to magnetic fields can lead to permanent damage to the movement, especially if the movement is repeatedly exposed to strong magnetic fields.

Electronic watches (quartz watches)

1. Malfunctions in the movement:
   • In quartz watches, magnetic fields can cause temporary or permanent malfunctions by disrupting the electronic circuit or the quartz oscillator frequency.
   • This can cause the watch to run incorrectly, lose time, or display other problems.

Protective measures against magnetic fields

• Magnetic shielding: Some high-quality watches contain magnetic shielding in the movement to protect it from external magnetic fields.
• Watch awareness: Watch manufacturers use special alloys or technological solutions to make watches more resistant to magnetic fields, for example by using anti-magnetic materials.
• Avoiding magnetic environments: Avoid wearing watches in environments with strong magnetic fields, such as near electrical devices, magnets, or MRI machines.

Summary Magnetic fields can have significant effects on the accuracy and functionality of watches, especially mechanical models. It is important to protect watches from strong magnetic fields to ensure precise timekeeping and long-term reliability. 14. How does an automatic movement work? An automatic movement, also known as a self-winding movement or automatic watch, is a mechanical movement that winds itself through the wearer's motion, without requiring manual winding. Here is a detailed explanation of how an automatic movement works: Basic principle of an automatic movement

1. Rotor and winding mechanism:
   • The heart of an automatic movement is the rotor, a semicircular oscillating weight that can move freely within the movement.
   • Through the wearer's natural movements (e.g. arm and hand movements), the rotor rotates around its axis.
2. Energy transfer:
   • The rotation of the rotor transfers mechanical energy to the movement.
   • This energy is used through a system of gears and springs to wind the mainspring (the spring that stores the energy).
3. Energy storage:
   • The mainspring is wound by the rotating movement of the rotor. This spring stores potential energy, which is then released in a controlled manner to power the watch.
4. Timekeeping and rate regulation:
   • The released energy drives the escapement, a mechanism that converts the energy into regular, even impulses that drive the watch hands.
   • The oscillation of the escapement is regulated by the balance wheel and hairspring to ensure precise timekeeping.
5. Power reserve:
   • An automatic movement has a power reserve that indicates how long the watch can run after being fully wound.
   • The power reserve depends on the size of the mainspring and the efficiency of the movement. Typically, the power reserve ranges from 24 to 48 hours or more.

Special features and care of automatic movements

• Wearing the watch: Regularly wearing an automatic watch ensures that the movement is continuously wound, as the wearer's natural movements activate the rotor.
• Watch winder: For watch enthusiasts who own several automatic watches and do not wear each one daily, a watch winder can be used to simulate the rotor's movement and thereby wind the movement.
• Maintenance: As with all mechanical watches, regular maintenance is important to preserve the function and longevity of the automatic movement. A service is recommended every 5-7 years, during which the movement is cleaned, oiled, and adjusted.

Advantages of an automatic movement

• Convenience: No manual winding required as long as the watch is worn regularly.
• Tradition and craftsmanship: Automatic movements are a sign of traditional watchmaking craftsmanship and often have a long history and development.
• Automatic chronographs: Many chronographs feature automatic movements that combine the function of a stopwatch with the convenience of automatic winding.

An automatic movement is a fascinating example of mechanical precision and elegance, drawing energy from the wearer's natural movement and thus keeping time reliably. 15. What are rate tolerances in a watch? The rate tolerance of a watch refers to the acceptable deviation of timekeeping from the actual time standard over a certain period. It indicates how accurately or inaccurately a watch runs and is usually stated in seconds per day. Here are some important points about rate tolerance: Definition and meaning

1. Accuracy:
   • Rate tolerance describes the average deviation of the watch time compared to a reference time, usually the official time standard.
   • It is measured by observing the watch over several days or weeks to determine the cumulative deviation.
2. Seconds per day:
   • Rate tolerance is often stated in seconds per day. For example, a watch may have a rate tolerance of +5/-3 seconds per day.
   • This means that the watch may either gain up to 5 seconds per day or lose up to 3 seconds per day and still be within the specified tolerance.

Factors that can affect rate tolerance

1. Type of movement:
   • Mechanical watches usually have a higher rate tolerance compared to quartz watches. The accuracy of mechanical watches can be influenced by various factors such as the quality of the movement, the condition of the lubrication, and the adjustment.
   • Quartz watches are generally more precise and may have a rate tolerance of only a few seconds per month.
2. Movement adjustment:
   • Precise adjustment of the movement by a watchmaker can improve rate tolerance.
   • Adjustment typically includes regulating the balance wheel or oscillator to optimize the oscillation frequency and therefore timekeeping.
3. Environmental influences:
   • Temperature fluctuations and how the watch is worn (e.g. worn daily or only occasionally) can affect rate tolerance.
   • Mechanical watches may be more sensitive to these factors, while quartz watches are generally less susceptible.

Importance of rate tolerance for watch owners

• A tighter rate tolerance means more precise timekeeping, which is important for those who have high standards for their watch's accuracy.
• Most high-quality mechanical watches have a rate tolerance of around +6/-4 to +2/-2 seconds per day.
• Watch enthusiasts and collectors often value watches with particularly good rate performance, as this is a sign of the movement's quality and precision.

In summary, a watch's rate tolerance describes its accuracy over a longer period and is an important criterion for the quality and performance of a movement. 16.
