Which watch suits me?
This depends primarily on what type you are and what requirements you place on a watch. The following table shows you a few constellations of type and watch.
Different models and the type
Automatic watch with leather strap
Aircraft watch with steel bracelet
flashy watches as eye-catchers
sporty smartwatches with high functionality, Digital watches
classic quartz watch in antique style
How big should my wristwatch be?
Whether it's a ladies' watch or a men's watch, the watch should not be too big because that always looks very ostentatious. Especially if you have a very narrow wrist, you should pay attention to the right size of your chronograph.
For this you can use the 18 to 40 rule. This states that a wrist with a maximum circumference of 18 centimeters should never wear a watch that has a larger diameter than 40 millimeters.
Which watch glass is the best for me?
Basically, you can divide the material of watches into three categories: Plastic Glass, Mineral Glass and Sapphire Glass.
Plastic glasses are made of polymethyl methacrylate and the common names are plexiglass, acrylic glass and hesalite glass. This material is very light, relatively impact resistant and you can polish it easily. However, it scratches quite quickly. Scratches can be repaired by polishing.
Mineral glasses have a higher scratch resistance and a higher degree of hardness, but they can still be scratched. If this is the case, they cannot be polished away as easily as plastic lenses.
Sapphire lenses are particularly impressive due to their enormous scratch resistance as well as their durability. If you do notice traces on the glass, these are usually not scratches, but residues that other materials have left on the sapphire glass. These can be easily removed with an eraser.
However, sapphire crystal also has a disadvantage: light refractions often cause unfavorable reflections.
What different movements are there?
Watch movements are divided into four categories: Hand-wound movement, automatic movement, quartz movement and radio-controlled movement.
You'll usually encounter a hand-wound movement on older watches. It is the true classic among the movements and convinces through sophisticated technology and historical significance. But the hand-wound watches have a big disadvantage: After about two days, they run out of energy. If you do not wind the watch in time, the movement stops and you have to reset it.
A hand-wound movement always consists of three components: Gear train (gears), drive and escapement. To start such a mechanical watch, you have to turn the crown on the watch case. The torque is transmitted to the spring movement and from there, with the help of the gears, to the escapement wheel. The exact torque is transmitted to the balance wheel. The balance is the oscillating system and serves as the rate regulator. It always oscillates back and forth, always with the same time interval. These oscillations are transmitted to the gears where the second, minute and hour hands are attached.
An automatic movement winds itself by the movement of your arm. To do this, they are equipped with a ball-bearing rotor. This stops in space due to inertia as soon as you move the watch case. The resulting forces exert a torque on the winding mechanism and the watch virtually sets itself.
The quartz movement has so-called bending oscillators in rod form, which represent a vibrating unit and allow higher oscillations to achieve better accuracy. The unit usually gets its oscillations from a battery, or from a mains supply if it is a large wall clock. A built-in coil passes the current to an oscillator, which sets the bending oscillator in motion. This drive requires very little energy, which is why quartz movements run very efficiently and remain operational for years on just one battery.
The bottom line is that the operating principle of a radio-controlled movement has not changed since the 1970s. In most countries around the world, transmitters have been installed which emit an exact time signal. A radio controlled movement intercepts this signal and relays it directly to your watch.
When is a wristwatch considered water resistant?
A wristwatch is considered water resistant when it can withstand at least five bar of water pressure. Five bar is equivalent to about 50 meters. However, this does not mean that you can dive 50 meters deep with such a watch. With a watch that can withstand five bar of water pressure, you can at most wash your hands.
Water pressure in bar for water resistance
Never take it in the shower, let alone swim
small splashes of water are no problem
suitable for hand washing
suitable for showering or Swimming suitable
can be used for diving
suitable for all water activities
How do I clean my watch?
The best way to clean your watch is with clean water and a dust- and lint-free cloth. If that doesn't help, use some washing-up liquid. This is usually fat-dissolving and does not attack the material of your watch.
In no case should you use aggressive cleaners such as bathroom cleaners or the like. Wristwatches are usually coated and suffer from aggressive cleaning agents. The material becomes dull and loses its luster.
Can I change the bracelet on all watches without any problems?
You can change the bracelet on any watch in any case, now whether this is done without any problems depends on your skill.
Most important is that the new bracelet has exactly the same width as the old.
How do I open my wristwatch to change the battery?
As a rule, wristwatches are either equipped with a pressure back or with a screwed watch case.
You can recognize a pressure back by a small notch, which you can best open with a pointed object. If you push it under the notch, you can easily lift the pressure back.
With a screwed watch case, you usually have to use special watch tools to get it open.
If you have opened the watch, you can simply remove the battery and insert a new one. I advise you to use tweezers to change the battery. Otherwise you might destroy important parts of the movement.
At what age is my child ready for a wristwatch?
This varies from child to child and usually depends on the learning ability of the offspring as well as the education of the parents. However, children usually become interested in a watch all by themselves at some point and want to be able to read it before they start school.
Thus, the perfect age for a children's watch is preschool age. From this age onwards, you can try to integrate clock reading into everyday life in a playful way. A children's alarm clock can be helpful here, by pointing to the hands each time before going to bed and explaining the position.
Furthermore, the preschool age is a good time, because children at this age must slowly get used to time processes.
What are smartwatches?
Smartwatches have functions that are equivalent to a smartphone. Internet access, telephony, SMS or Whatsapp are not uncommon with these watches. Moreover, you can also enjoy the full range of audio and video playback with a smartwatch. For this purpose, they are usually equipped with a built-in sim card or you connect the watch via Bluetooth with your smartphone.
In addition, smartwatches usually offer even more functions that are very helpful, especially in the sporting field. For example, you can play sports with them and they show you heart rate, distance, pace and other important information.
