Frequently Asked Questions - 7N42 Lorus
How do I set the time on my Lorus 7N42?
Pull the crown to position 2 and rotate it to set the desired time. Push the crown back in after setting.
How do I set the date?
Pull the crown to position 1 and turn it forward until the correct date appears. Make sure to avoid setting the date between 9 PM and 3 AM to prevent damage.
Is the Lorus 7N42 waterproof?
The watch is water resistant to 3 ATM, which means it can withstand minor splashes and rain, but it is not suitable for swimming, diving, or showering.
What type of battery does the 7N42 use?
It typically uses a silver oxide battery, commonly SR621SW or an equivalent. Replacement should be done by a professional to maintain water resistance.
How long does the battery last?
Under normal conditions, the battery lasts approximately 2 to 3 years. Heavy use of additional functions may reduce this.
How do I clean my watch?
Use a soft, dry lint-free cloth to wipe the case and bracelet. Do not use any chemical cleaners or ultrasonic baths.
Can I replace the battery myself?
While it is possible with special tools, it is recommended to have it replaced by a watchmaker to ensure the case remains sealed and water resistant.
What should I do if my watch stops?
First, check if the crown is fully pushed in. If it still doesn't run, the battery may be depleted. Replace the battery or consult an authorized service center.
Can I adjust the metal bracelet length?
Most Lorus 7N42 models have a deployant clasp with removable links. You can adjust it at home using a pin pusher, or have a jeweler do it for you.
How do I care for a leather strap?
Keep the leather strap away from water and moisture. Clean it with a slightly damp cloth and condition it periodically with a leather product.
