Frequently Asked Questions - Postojna Holzkern
How do I set the time on my Holzkern Postojna watch?
Pull the crown out to the second position and rotate it until the hands show the correct time. For models with a date function, pull the crown to the first position to adjust the date. Push the crown back in after setting.
Is the watch waterproof?
The watch has a water resistance of 3 ATM, which means it can resist splashes and brief rain, but it is not suitable for swimming, showering, or diving. Keep it away from water whenever possible.
How do I change the battery?
The watch uses a SR626SW battery. To replace it, remove the case back (preferably with a professional tool) and insert a new battery with the positive side facing up. We recommend having the battery changed by a jeweler to avoid damaging the case.
Can I swap the strap?
Yes, the strap is interchangeable. Use a spring bar tool to remove the old strap and attach a new one with the same width (20 mm). Holzkern offers a variety of replacement straps.
How should I clean and maintain the wooden case?
Use a soft, dry cloth to gently wipe the wood. Avoid water, soap, and alcohol, as they can damage the natural wood. Apply a small amount of wood polish occasionally to maintain the luster, but make sure it does not touch the movement.
What is the warranty period?
Holzkern provides a 2-year international warranty against manufacturing defects. The warranty does not cover damage caused by improper use, normal wear, or water damage.
Does the watch have a date function?
Yes, the Holzkern Postojna features a date window at the 3 o'clock position. To adjust the date, pull the crown to the first position and turn it clockwise.
What type of movement does it use?
It uses a Japanese quartz movement, known for its accuracy and reliability. It requires a single battery and has a typical lifespan of 2-3 years.
Is the watch suitable for everyday wear?
Absolutely. The natural wood case and genuine leather strap make it a stylish and comfortable accessory for daily use. However, you should avoid exposing it to extreme conditions such as direct heat, moisture, or impacts.
How can I adjust the bracelet length?
When the strap is leather, you can adjust it using the buckle holes. If you need additional holes, use a leather hole punch. For a wooden bracelet, you may need to remove links with a pin tool, but we recommend consulting a professional.
