BA111OD specializes in mechanical watches. It's crucial to understand the difference between our automatic mechanical watches, which operate based on daily movements. These timepieces continually recharge themselves using an oscillating weight at the back of the watch.

On the other hand, our Chapter 4. Tourbillon collection features manual mechanical watches. Unlike the automatic variants, these manual timepieces do not have an oscillating weight and thus, need to be manually wound periodically using the crown to function optimally.

This distinction ensures that you choose a watch that aligns perfectly with your lifestyle and preferences.

An automatic mechanical watch consistently recharges itself with your daily movements. However, it’s crucial to note that even with everyday use, day-to-day movements may not fully recharge the watch to ensure the intended power reserve. That’s why it’s essential to occasionally manually wind the crown to fully charge the mechanism. The procedure is straightforward:

• Let the crown rest against the watch case.
• Turn the crown upwards with your thumb.
• You’re now manually winding the watch and may hear a slight noise.
• To fully recharge the movement, make about forty turns.

This simple practice ensures your watch operates with optimal precision, reflecting the exceptional quality and reliability of your BA111OD timepiece.

Manual winding watches absolutely require winding through the crown. When your watch is nearing the end of its power reserve, the mechanism may lose full performance and could start to lag. Hence, it's crucial to wind it occasionally while it’s working to prevent it from stopping.

Here's how you can do it:

• Let the crown rest against the watch case.
• Wind the movement by turning the crown upwards using your thumb.

Unlike automatic movements, with manual movements, you will feel a noticeable pressure when the movement is fully wound. Once your watch is completely charged, avoid further winding as it risks damaging the movement. This tactile indication helps to ensure the longevity and precision operation of your cherished manual BA111OD watch.

The power reserve is a figure that tells you how long your watch should operate once it's fully wound. This number lets you know how much time your watch will continue to function, even if you're not wearing it (for automatic watches). For manual mechanical movements, it indicates the operating time of your watch before it will gradually stop and will need to be wound again using the crown.

Some of our crystals and straps feature integrated NFC (Near Field Communication) chips, a technology that allows easy information exchange with compatible mobile devices. No app is typically required—simply bring your mobile device within 1 cm of your watch crystal or strap to connect.

Moisture, sweat, and water don’t significantly impact your watch strap, but they can accelerate its wear and tear. It's important to note that our watch warranty does not cover the straps. Should you wish to acquire a new strap, feel free to contact us directly. We would be happy to present you with new strap options and provide their prices. This way, you can ensure your BA111OD watch always looks and feels its best on your wrist, ensuring comfort and style in every wear.

Most of our straps come with the easy-clip feature. This function allows you to easily and hassle-free change the strap on your timepiece. To change your watch strap, simply pull on the bar that extends beyond the strap and shift it to the side to remove it from the watch.

To attach a new strap:

1. Insert one side of the bar into one of the holes of the lug.
2. Then, pull the bar to fit the other side.
3. Once done, find the other hole on the side that needs to be inserted.
4. You will hear a slight noise indicating that the spring of the easy-clip system has expanded.

Now, your new strap is on your precious timepiece. This convenient feature ensures that your BA111OD watch can seamlessly adapt to your style changes and wear preferences, keeping it as versatile and functional as you need it to be.

Just like other leather goods, a leather strap demands attentive care to retain its enduring elegance. Protect the leather straps from elements like water, sweat, and humidity, as well as grease, perfume, and chemical or cosmetic products. Make sure to limit their exposure to the sun to preserve their luster and suppleness over time.

No, this is impossible. On the same principle as the bank card is only active during contactless payment, the application on the phone is only activated when it is less than 1cm from the watch for a few seconds. And in this case, the chip does not have access to the data stored in the phone.

No, because there is voluntarily no intrusion in the mechanical movement.
