FAQs

Aerowatch has been manufacturing watches for more than 100 years.

Watches that were manufactured more than 15 years ago are no longer listed in our current database.

It is impossible to give information on models without examining them.

If you wish, we can carry out a precise expertise of your timepiece (production date, reference, material, etc...) for the sum of CHF150 + shipping costs. In this case, please send us your watch.

We will provide you with a certificate of origin. At the same time, we can, if possible, send you a quote for the repair of your watch.

The current value of your watch depends completely on the fluctuations of the vintage watch market. We recommend you to contact a company specialising in the sale of historical models on the current market.

In case of theft and providing the information is available, Aerowatch will directly inform the police of the retail price at its date of purchase.

Shocks: Whether thermal or other shocks, avoid them. In the event of violent shocks, please have your watch checked by an authorized service centre.
Crown: push it in carefully to the middle case to avoid water infiltration into the mechanism.
Temperatures: Do not expose your watch to sudden temperature changes (for example: exposure to the sun followed by immersion in cold water). Also avoid extreme temperatures above 50°C or below 0°C.

Chemical products: avoid direct contact with solvents, detergents, perfumes, cosmetics etc., which can damage the bracelet, plating, case or gaskets.

Magnetic fields: Do not expose your watch to strong magnetic fields such as a loudspeaker, refrigerator, or electromagnetic device.

The accuracy of an Aerowatch timepiece depends on its movement and the habits of its user, so it is variable.
The majority of mechanical and automatic watches have an average daytime running variation of 0 +15 seconds per day.

For optimal accuracy, an automatic watch should be worn on the wrist for 10 hours a day. After a prolonged stop, it is imperative to wind the crown about thirty times so that the mechanism has enough energy.

Hand-wound mechanical watch: it is necessary to wind the watch regularly by turning the crown manually.

Mechanical automatic watch: the watch winds up thanks to the movements of the owner's wrist.

If your Aerowatch timepiece stops, turn the hands manually with the crown in the pulled out position. When they indicate 12:00, if the day and date change, it is midnight. Set the time to noon and adjust the day and date. The day/date mechanism is active between 9pm and 2am. Make sure you do not set the day or date during this period. Concerning the moon phase : it jumps simultaneously at the date and are therefore not independent of each other. To make the adjustment, you need a lunar calendar and locate either the date of the last full moon or the last new moon (black moon). Then, you will have to be patient and turn the crown to position 2 (intermediate) until the date corresponds: either to the last full moon or the last new moon. Then, you will just have to count the days until the current day and synchronize it.

PVD stands for "Physical Vapour Deposition".
It is a sophisticated vacuum process in which microscopic particles are deposited on the products by ion bombardment or sputtering to form a protective surface.
This results in very thin layers of impurity-free components with high levels of hardness (nitride, carbides, etc.) and hypoallergenic qualities.

This water resistance marking on the case back indicates the depth to which the movement is protected from dust, moisture, and any damage that may occur if it is submerged in water. A watch is waterproof thanks to its gaskets. To ensure waterproofness, it is advisable to replace the gaskets every two years from the date of first use. It is also advisable to check the water resistance of your watch case every year if it has been exposed to seawater or pool water for long periods.

If the watch has been used in seawater, rinse it recto - verso with fresh water, and then dry it properly.
Aerowatch timepieces are not equipped with screwed crowns. Make sure that the crown is always correctly pushed against the case middle.

Never adjust the crown or the pusher while submerged in water because it may leak into the case. It is best to remove your watch before taking a shower or bath and before entering a sauna or steam room because heat, soap and steam can prematurely age the water resistant gaskets.

We do not recommend completely submerging your watch in water to avoid damaging the leather strap.

If there is condensation under the crystal, it means that water has infiltrated the watch. It must be checked as soon as possible.
It is important to remember that the water-resistance of a watch is tested at a specific time and is not guaranteed for life. Any intervention on the case or significant temperature variations (such as a cold shower after sun exposure) as well as the ageing of the materials can lead to moisture infiltration into even the most waterproof watch.

Servicing your Aerowatch timepiece will help you preserving its longevity over the years. We recommend that you carry out a waterproof test every 2 years and a complete service every 4 to 5 years.

A full service takes between two and five weeks, depending on the condition of your watch. Before a service is performed, a watchmaker examines your watch to establish a diagnosis. After that, the watchmaker determines which interventions will be necessary. An estimate will then be made.
The cost will depend on the type of service requested and the condition of the watch. For more details, please contact your official Aerowatch dealer or Aerowatch Customer Service directly.

Please note that in case of refusal of the quotation, you will be charged the administrative fee of CHF 30.00.

To measure your wrist size, you must bring a tape or a string. Wrap your wrist loosely, the ideal way is to slip a finger under the tape (see diagram). Note the measurement by adding a half-centimetre.
For an "exact size" wear: use your measurement.
For a "close to the skin" wear: add 1 to 1.5cm to your measure.
For a "loose" fit: add 1.5 to 2cm to your measure

The average size of bracelets is around 18cm for women and 20cm for men.

Measure your wrist size using the wrist measurement tool available. 

We can offer machine engravings on steel watches; e. g. anniversary date or initials.

Each watch has its own reference number, for example the model Renaissance Skeleton Cobweb in steel (reference: A 50981 AA19). The reference number is indicated on the documents given to you at the time of purchase, such as the international warranty certificate.

The first two digits correspond to the movement number (calibre). You can therefore download the manual instructions of your watch under the following link by choosing the right calibre.
The next three digits of the reference correspond to the case reference and the letters correspond to the case material.
The last two digits refer to the dial reference.
To correctly identify your Aerowatch model, you need 9 characters.
