* It is recommended to use the watch carefully, following the above operating instructions. Before use, check for the water resistance marking on the dial or case back.
Impact Resistance
Remove your watch during energetic sports activities; however, sports like golf will not negatively affect the watch's condition. Avoid strong impacts, such as dropping the watch on the floor.
Magnetic Fields
Do not expose the watch to strong magnetic fields for extended periods, as internal components may become magnetized, leading to malfunction. Exercise caution. Under the influence of a magnetic field, the watch may temporarily run fast or slow. Accuracy will be restored once the magnetic field is removed. In such cases, reset the time.
Vibration
The watch may lose accuracy if subjected to strong vibrations, such as those caused by riding a motorcycle, using a jackhammer, or a chainsaw.
Temperature
The watch may run incorrectly or stop if exposed to temperatures below or above the normal range (5°C – 35°C). [!] WARNING Do not use the watch at high temperatures (e.g., in a sauna). The watch may become hot and cause burns.
Chemicals, Gases, etc.
Exercise maximum caution when in contact with gases, mercury, chemicals (paint thinner, gasoline, various solvents, detergents containing such substances, adhesives, paints, medicines, perfumes, cosmetics, etc.). These substances can change the color of the watch case, bracelet/strap, and dial. Changes in color, deformation, and damage to polymer components are also possible.
Additional Precautions
Additional Parts
[!] WARNING
Do not give bracelet pins/straps and other small parts to children. In case of swallowing a small part, seek medical attention immediately.
Allergic Reactions
[!] ATTENTION
If a rash or irritation appears on the skin after contact with the bracelet, stop wearing the watch and consult a doctor immediately.
Luminescent Coating
Some models feature luminescent coating on the hands and bezel. It is made from safe, non-radioactive paint that absorbs sunlight and artificial light, emitting it in the dark. As it emits stored light, the coating gradually becomes dimmer. The amount of emitted light and duration of luminescence depend on various factors: glass shape, paint layer thickness, ambient light brightness, distance from the light source, and light absorption degree. Note that if little light is accumulated, the watch will glow weakly or for a short time.
Waterproof Strap
Some models use leather and nylon straps that have undergone special treatment for protection against sweat and water. The waterproof property of this strap may be lost depending on the period and conditions of use.
Technical Specifications
- Oscillation frequency: 21,600 vibrations/hour
- Number of jewels: 21 jewels
- Daily accuracy: from +25 sec. to -15 sec.
- Power reserve: over 40 hours
- Date indicator
- Shock-resistant bearings for protecting the balance wheel with a hairspring from impacts.
- Interchangeable image: Seven images change automatically in order daily. You can also manually select an image by pressing the button twice.
The stated daily accuracy is ensured under the following conditions: After 24 hours of being kept at room temperature, with the mainspring fully wound and the dial facing upwards.
Technical characteristics of automatic watches may cause deviations from the stated daily accuracy; these are influenced by factors such as daily wearing duration, watch position, hand movement, and mainspring winding conditions.
Technical specifications are subject to change without prior notice due to product modernization.
[!] ATTENTION
It is not recommended to set the date or interchangeable image between 10:00 PM and 4:00 AM, as date and image changes occur during this period. If the date or image is set during this time, the date may not change correctly, or the watch may malfunction. When setting the date or image, always move the hour and minute hands to a different time period.
Models with Screw-Down Crown
On some models, you cannot pull out the crown without unscrewing it (models with a screw-down crown).
To operate watches of this type:
- Before setting the date, time, or interchangeable image, turn the crown counter-clockwise to unlock the screw.
- Before setting the date, time, or interchangeable image, push the crown in and turn it clockwise until it stops to lock the screw.
Automatic Movement Mechanism
This watch is mechanical and features an automatic winding function.
When worn on the wrist, the mainspring is wound by natural hand movements.
If the watch stops, shake it at least ten times to start the second hand. After the second hand starts moving, set the date, time, and interchangeable image.
With a full wind, the watch will run for approximately 40 hours. If the watch is not sufficiently wound, its accuracy may differ from the stated value. To ensure accuracy, it is recommended to wear the watch for at least 8 hours a day.

* The image changes each time the button is double-pressed. (If the button is pressed only once, the image does not change.) Press the button to select the desired image. There are a total of seven different images.
For models with a button that cannot be pressed by finger (models with a hidden button): To change the image, use an object with a pointed end (precision screwdriver, tweezers, etc.) to press the button and select the desired image.
