How can I charge my smartwatch?
Each model comes with a USB charging cable. Ideally, you should charge your Smartwatch using your computer's USB port.
Alternatively, you can use a power adapter with a maximum output of 5V.
You should pay attention to the voltage being supplied to the device, as exceeding this may cause the Smartwatch to stop working
What is the funcion "Reset" for?
The “Reset” option allows you to restore the smartwatch to its factory settings.
When performing a reset, all data on the smartwatch will be erased, including custom watch faces, settings, and daily information.
The app functions as a mirror of the smartwatch's data. Therefore, when resetting the smartwatch:
The data from the current day will be deleted from the app;
Records from previous days will be retained.
This feature is ideal for:
Resolving technical issues;
Preparing the device for a new user.
Compatibility with One Smart, One Time Pro, and Lefun Health Apps
The ONE SMART App is compatible with the following generations of mobile phones
The ONE TIME PRO App is compatible with the following generations of mobile phones:
The ONE TECH PRO App is compatible with the following generations of mobile phones
The LEFUN HEALTH App is compatible with the following generations of mobile phones:
This means that mobile phones from the last 10 years are compatible with APP ONE. On iOS the App "talks" to the Health App on the mobile phone and the health data stays in that app.
Call Function – Making and Receiving Calls
Is the number of frequent contacts limited?
Yes! Each One App has a limit to how many frequent contacts you can add. To do this, open the app, select “Frequent Contacts”, and then tap the “+” icon to add to the list. Synchronization is automatic, and the selected contacts will appear on your smartwatch under “Frequent Contacts.”
If you want to update the list, you’ll need to edit it directly in the app by following the same steps.
One Smart App — 8 frequent contacts
One Tech Pro App — 10 frequent contacts
One Time Pro App — 10 frequent contacts

Why does Bluetooth disconnect by itself?
The maximum distance between the smartwatch and the phone is 8 meters in a straight line. The connection may be affected by:
Direct sunlight
Electronic interference with Bluetooth
Walls or doors
Once paired with the app, the smartwatch will automatically reconnect when it is within range.
If the smartwatch moves out of Bluetooth range, the connection will be lost.
The app automatically detects the smartwatch as soon as it is opened.
I broke the screen of my smartwatch: Is there a way to repair it?
If you purchased your smartwatch online or at one of the official One stores, you can contact us via email at info@onewatchcompany.com or visit any One store or kiosk to request Technical Assistance.
If the purchase was made through an authorized reseller, we recommend that you first visit the store where you made the purchase.
If that’s not possible, you’re also welcome to visit any of our stores or kiosks, where we’ll be happy to assist you.
Important:
The warranty may not cover damage such as screen cracks or scratches.
In such cases, a non-binding repair estimate will be provided, and the repair will be carried out only with your approval.

I had a skin reaction while wearing a One Smartwatch. Is that possible?
Follow the steps below to make sure your smartwatch works normally and looks good. Otherwise, you may damage your smartwatch and cause skin irritation:
1. Make sure that the protective plastic over the biometric glass is removed;
2. As a rule, the reaction happens whenever sweat accumulates on the wrist (this happens with any watch, due to the sensitivity of the skin to humidity);
3. The third reason is an extension of the second, there is a possibility of accumulation of debris around the biometric sensor, likewise, it should be cleaned regularly. In traditional watches, the simplest ones have a flat bottom, in which case there is less chance of this happening. However, the allergy is not due to any material used on the back of the watch, as plastic is allergy-free.
4. After exercising or sweating, clean your wrist and strap. Use water to clean the smartwatch and dip a small amount of alcohol in a wipe, then dry it thoroughly.
5. Protect the smartwatch from dust, sweat, paint, oil and chemicals (such as cosmetics, antibacterial sprays, hand sanitisers, detergents and insecticides). Otherwise, internal and external parts may be damaged or affect the performance of the smartwatch. If the smartwatch is stained with these substances, clean it with a soft, lint-free wipe.
NOTE - The best solution for the scenario described above is to wipe the smartwatch, namely the back of the watch and the strap with a soft damp tissue to remove traces of sweat (do not use soap, detergent, abrasive materials, ultrasonic waves or external heat sources. Otherwise, your smartwatch may be damaged).
Residues of soap, detergent, hand sanitiser or detergent may cause skin irritation.
Avoid wearing this or any watch until the irritation goes away, after which the problem should be resolved
How do the smartwatch sensors work?
Smartwatches are equipped with a compact, integrated biosensor designed for low power consumption, allowing for battery life of over 24 hours.
The smartwatch uses optical technology (LED + sensor) to measure data through the user's skin.
For the smartwatch algorithms to function properly and provide more accurate measurements (such as calories burned, heart rate, and other wellness data),
  
it is essential that users enter their real personal information (such as age, weight, height, and gender) in the app settings.
Incorrect or incomplete information can compromise the reliability of the results displayed.
What can you do to ensure greater accuracy in the measurements?
How does sleep tracking work?
Sleep is recorded during specific time intervals. Outside of these periods, the smartwatch will not track sleep — even if you are sleeping.In the One Smart App, sleep is tracked from 8:00 PM to 10:00 AM.In the One Time Pro and One Tech Pro Apps, sleep is tracked from 9:30 PM to 12:00 PM (noon).
Can my Smartwatch replace a medical device?
The measurements taken by the smartwatch are not intended for medical purposes and should not be used for diagnosis, clinical monitoring, or as a substitute for professional medical advice. They are intended solely for general fitness and wellness purposes.
Step count
Step counting on a smartwatch without integrated GPS is usually performed using an accelerometer built into the device. The accelerometer is a sensor that measures movement. It detects the changes in movement and orientation of your wrist as you walk, allowing you to estimate the number of steps taken. When we walk, the accelerometer detects the movement and converts this information into digital data. The smartwatch uses specific algorithms to analyse this data and identify characteristic step patterns. Based on these patterns, it calculates the number of steps taken.
Step counting algorithms may vary between different smartwatch models and manufacturers.
It is important to mention that step counting on smartwatches without GPS may not be as accurate as on devices with integrated GPS, as there is no location data to assist in determining the distance walked.
My smartwatch isn't showing the time correctly. What can I do?
The "delay" occurs because the phone's bluetooth is not sending the data fast enough to the smartwatch.
The delay is not related to the physical distance between the watch and the phone, but probably a software problem in the phone itself.
Follow the steps below in sequence:
1. Disconnect the watch from the ONE App (remove it from the APP);
2. Uninstall the APP from all the phones to which the watch was previously connected (if any of them are Iphone you will have to do "forget" on Bluetooth);
3. Reset the watch (Reset button on the smartwatch);
To make sure it's the phone that's the problem, not the watch, you can try this very simple experiment.
After Step 3 above, when the smart is reset, it will show you 10am. It will point to the actual time of day at that precise moment, and check the smart again in 24 hours - if the watch shows 10am again after 24 hours, that means the smart is neither "Behind" nor "Ahead".
4. Install the APP again and connect the watch again.
It is important that in Step 1, the watch is removed from the APP before following the other steps.
Make sure that the time setting is in AUTOMATIC MODE, not manual.
Also, check that the time zone is correct in the phone settings.
Phones usually work outside of the network time and smartwatches are even more accurate than regular watches as they synchronise the time down to the last second.
Can I get my Smartwatch wet or swim with it?
No. Although our smartwatches are labeled as water-resistant, it’s important to note that they are not waterproof. Our devices are designed to withstand minimal exposure to water, such as splashes or light rain, but they are not suitable for underwater use.
It is essential to avoid exposing our smartwatches to water-based activities such as swimming, bathing, or diving, as this can damage the device and void the warranty.
We encourage users to exercise caution and ensure their smartwatches remain dry to maintain their functionality and longevity.
I read all the questions but I still have doubts.
If you have any questions about using your smartwatch, please contact our support by email. We will assist you as soon as possible.

What care should be taken with watches?
In order for your watch to work in perfect condition, we recommend the following precautions:
- As the water resistance of watches differs depending on the model, you should always check this information on the case cover to find out what types of use are supported in each water resistance category;
  
- The crown should be in its normal, tightened position to ensure the advertised water resistance;
  
- You should never set the watch or operate the buttons or rotating bezel while the watch is wet;
  
- Whenever you change the battery of the watch, you should also change the seal of the cover to not compromise the watertightness of the watch;
  
- If the watch has stones or crystals on the outside, you should take some additional care - avoid contact with water, perfumes or other substances that may interact with the materials - to prevent the stones or crystals from coming loose, becoming discolored or stained.
Are watches waterproof?
What does water resistance mean?
"Water resistance" refers to the watch's ability to withstand specific water pressures in a laboratory environment.
To ensure that your watch doesn't get damaged when engaging in activities where it may be subjected to higher pressures, you should always check your watch's water resistance rating. If your watch can handle the pressures of that activity, you should also ensure that the crown is properly closed and that you do not use either the crown or the buttons.
Even in water-resistant watches, damage can occur with hot water or saltwater, as this contact can harm the seals. These seals may also experience wear and tear depending on usage, and therefore, they should be regularly replaced to ensure that the watch remains watertight.
If condensation appears on your watch's dial, you should immediately contact us via email at info@onewatchcompany.com or visit an authorized retailer.
How is the size of a watch measured?

My watch is running backwards/fast forwards. What does it mean?
The second hand on my watch seems to move unevenly. what does it mean?
Are watches protected against drops or bumps?
What care should be taken with jewelry?
In order for your jewellery to maintain its characteristics over time, we recommend the following care:
- Avoid contact with fresh or salt water, perfumes or other substances that may interact with the materials, discolouring or staining them;
  
- Do not wear while sleeping or practising sport;
  
- Avoid subjecting the jewellery to sudden or continuous strong contact that may cause friction and scratch or deform the piece;
  
- Gently wipe with a chemical-free silver polishing cloth to restore the luster of the piece and remove minor blemishes.
What are jewelry made of?
How can I find the right ring size?
A ring of the right size should be comfortable, being tight enough not to fall off and loose enough to slip on the finger. The simplest way to find your size is to measure the diameter of a ring you already have, as shown in the picture below, and compare it with the table below:

If your measurement falls between two sizes, you should opt for the larger size.
  
Alternatively you can measure your finger, but to ensure you find the right size, you should take several measurements at different times and days as the size of your finger varies throughout the day and depending on the weather. You should avoid using materials that can stretch or twist, as they may register an incorrect measurement.
If you have any questions or need help, you can contact our Customer Support via the contact form or by sending an email to info@onewatchcompany.com.
