Using your new men's mechanical wristwatch is a breeze. Just put it on like any other watch and the automatic self - winding movement will start working as you move your arm. Since it's not waterproof, avoid getting it wet, like when you're washing hands or in the rain. To keep your watch in top shape, wipe it gently with a soft cloth regularly. Store it in the provided paper box when not in use to protect it from scratches. And remember, although it has a durable stainless - steel case and premium leather band, treat it with care for long - lasting performance.
