Welcome to the Ollech & Wajs adventure
Thank you for choosing an Ollech & Wajs watch, or OW for short, one of the world's most renowned Swiss brands.
Carefully crafted using high-quality materials and components, it
is protected against shocks, temperature variations, water, and
dust.
For perfect and precise operation of your watch for
many years, we recommend that you carefully follow the
instructions given below.
These instructions apply to all OW automatic mechanical watches.
Important information
To ensure even better water resistance, our models
are equipped with a screw-down crown. Before setting the
time, winding, or adjusting the date, it is
necessary to unscrew the crown to position IB.
Important: After any handling, it is essential to screw the crown back on to maintain the watch's water resistance.
Winding
It is necessary to manually wind your watch if it has stopped or
has not been worn for several days, in order to ensure the continuous operation
of your watch during periods of low activity (e.g., while
sleeping).
In these cases, turn the crown forward approximately 30 times in
position I. The automatic winding system will then fully wind the movement if the watch is worn. It is also possible to fully wind an automatic watch manually using the
winding crown. However, please note that automatic movements
have a slipping clutch that disengages the winding system (the crown
can be turned indefinitely) when the movement is fully wound.
Generally, 80 turns of the crown are sufficient to fully wind
most automatic mechanical watches..
The efficiency of the automatic winding system of a mechanical movement depends on the wrist movements of the wearer. Do not intentionally shake your automatic watch to wind it; this is ineffective and could damage the watch.
Settings
Time setting
Pull the crown out to position 3 and turn it forward or backward
until you reach the desired time.
Synchronize the time with an official time signal (radio/TV/Internet).
When the crown is pulled out to position 3, the seconds hand stops. Once the time is
synchronized, push the crown back in to position 1 and screw it back in.
Quick date correction
Caution: Do not perform a quick date correction between 10 PM and 2 AM.
Pull the crown out to position 2 and turn it forward until the desired date is displayed.
During this operation, your watch will continue to function and will not need to be reset..
Chronograph
Caution: Do not perform rapid date corrections between 10 PM and 2 AM.
Use the setting button at 10 o'clock; pressing it advances the date by one day.
Technical information
Power reserve
OW automatic watches draw their energy from an oscillating weight
activated by the natural movements of your wrist.
This weight winds the watch. Automatic watches do not
require a battery. Depending on the model, the power reserve varies from
36 to 54 hours.
Precision
The accuracy of a mechanical watch depends on the wearer's movements and habits, and can therefore vary. A qualified OW watchmaker can adjust the accuracy of a watch within OW's tolerance limits.
Most watches that are not chronometer-certified have an average accuracy tolerance of around -6 /+15 seconds per day.
A chronometer is a high-precision mechanical watch that has obtained an official certificate issued by the COSC (Official Swiss Chronometer Testing Institute) after its movement has successfully passed several accuracy tests in different positions and at different temperatures, as well as water resistance tests, carried out in a laboratory for 15 days and 15 nights. To obtain the title of chronometer, the average accuracy of the mechanical movement must be between -4/+6 seconds per day.
Water resist
OW watches are designed to withstand pressures up to 30 bar (300 m / 1000 ft), 50 bar (500 m / 1650 ft), and 100 bar (1000 m / 3300 ft), as indicated on the case back. However, the absolute water resistance of a watch cannot be guaranteed at all times. It can be affected by the aging of the seals or by accidental impact. We recommend having the water resistance checked annually by an authorized OW service center.
Care and maintenance
Temperature
Do not expose your watch to sudden temperature changes (exposure to sunlight followed by immersion in cold water) or to extreme temperatures (above 60°C or below 0°C).
Magnetic fields
Do not expose your watch to strong magnetic fields such as those emitted by speakers, mobile phones, computers, refrigerators or other electromagnetic devices.
Shocks
Avoid thermal or other shocks: they could damage your watch. In case of a severe impact, please have your watch checked by an authorized OW service center.
Harmful products
Avoid any direct contact of your watch with solvents, detergents, perfumes, cosmetics, etc.: they can damage the strap, the case or the seals.
Cleaning
We recommend regularly cleaning your watch (except for the leather strap) with a soft cloth and lukewarm soapy water. After swimming in salt water, rinse your watch with fresh water and let it dry completely.
Services
Like any high-precision instrument, a watch requires periodic servicing to function optimally. As a general rule, we recommend having your watch serviced every 3 to 4 years by your authorized OW retailer or service center. However, please note that this interval may be shorter depending on the climate and how the watch is used. To ensure impeccable service and maintain your warranty, always contact an authorized OW retailer or service center.
